Hereditary breast cancer: ever more pieces to the polygenic puzzle
Hereditary Cancer in Clinical Practice volume 11, Article number: 12 (2013)
Several susceptibility genes differentially impact on the lifetime risk for breast cancer. Technological advances over the past years have enabled the detection of genetic risk factors through high-throughput screening of large breast cancer case–control series. High- to intermediate penetrance alleles have now been identified in more than 20 genes involved in DNA damage signalling and repair, and more than 70 low-penetrance loci have been discovered through recent genome-wide association studies. In addition to classical germ-line mutation and single-nucleotide polymorphism, copy number variation and somatic mosaicism have been proposed as potential predisposing mechanisms. Many of the identified loci also appear to influence breast tumour characteristics such as estrogen receptor status. In this review, we briefly summarize present knowledge about breast cancer susceptibility genes and discuss their implications for risk prediction and clinical practice.
Hereditary breast cancer has been formally investigated since the middle of the 19th century [1–3]. About thirty years ago, epidemiological and genetic linkage studies of multiple-case families have guided the identification of TP53 mutations as a cause of Li-Fraumeni Syndrome [4–6] and of BRCA1 and BRCA2 as first genes in which mutations strongly predispose to breast and ovarian cancer [7, 8]. There are further rare syndromes which include the occurrence of breast cancer as part of the disease spectrum, and the underlying genes have been identified by positional cloning. Apart from Li-Fraumeni Syndrome, these include Cowden Disease (PTEN) [9, 10], Peutz-Jeghers Syndrome (LKB1/STK11) [11, 12], Lynch Syndrome (MSH2,MLH1) , Bloom’s Syndrome (BLM)  and Ataxia-Telangiectasia (ATM) . In addition, familial lobular breast cancer has been associated with germ-line mutations in CDH1, the gene for E-cadherin [16, 17]. Although the above-mentioned syndromes are rare, they need to be kept in mind if a breast cancer patient presents with a more complex disorder or suspicious family history. For the recessive Ataxia- Telangiectasia and Bloom’s Syndrome, the monoallelic occurrence of mutations predisposes heterozygous carriers outside of syndrome families to cancer, as will be described in more detail below.
While the identification of genes underlying these syndromes has been largely achieved through linkage analysis of large multiple-case pedigrees and positional cloning, these genes represent only a small subset of the estimated heritable fraction and further linkage studies have been unfruitful. However, hereditary breast cancer syndromes only mark the extreme end of a wide spectrum of genetically influenced breast carcinomas. During the past years evidence has been accumulated that breast cancer is a polygenic trait and also that several more susceptibility genes exist [18–21]. Their mutations have differential impact according to the minor allele frequencies and the magnitude of the allelic effect, which generally show an inversely proportional relationship (Figure 1) . In the following, we briefly summarize present knowledge about breast cancer susceptibility genes and discuss their implications for risk prediction and clinical practice.
Identification of breast cancer susceptibility alleles
The most common methods to explore the genetic basis of hereditary breast cancer have been family and linkage studies, candidate gene sequencing and case–control association studies. This has led to the identification of rare mutations conferring intermediate or high risks for breast cancer (with relative risks above two-fold) as well as multiple common polymorphic loci that harbour low-penetrance alleles.
Rare mutations with a high to intermediate penetrance:
Genes harbouring breast-cancer associated mutations with an estimated high or intermediate penetrance as summarised in Table 1. Many of them have turned out to encode proteins that act in concert with each other in an intracellular DNA damage signalling and repair network that responds to double-strand breaks or interstrand crosslinks and ensures the error-free damage removal through means of homology-directed recombinational repair (Figure 2). Nevertheless, lifetime risks can be quite different between the genes as will be described in more detail below.
- BRCA1 and BRCA2: The prototypic BRCA1 and BRCA2 mutations confer a very high life-time risk for breast cancer in the range of 55-85% for BRCA1 and 35-60% for BRCA2, compared with an about 10% population risk [60–62]. Life-time risk for ovarian cancer is also high and may be up to 40% for BRCA1 mutation carriers. Importantly, both the risks for breast and ovarian cancer can also be modified by additional gene loci such as SNPs in RAD51 or BNC2 (Refs. [63–65], and see below). The spectrum of tumours in families segregating BRCA1 and BRCA2 mutations includes pancreatic, prostate, colon and skin cancers. Monoallelic BRCA2 mutations have also been associated with male breast cancer and have been observed in Li-Fraumeni families. Biallelic mutations in BRCA2 give rise to the recessive developmental disorder, Fanconi Anemia D1 . In case of BRCA1, homozygosity for severe mutations has not been confirmed and may be embryonically lethal. However, compound heterozygosity for two BRCA1 mutations, one of them apparently hypomorphic, has been described in a single patient with short stature, microcephaly and early ovarian cancer . Consistent with these findings, the BRCA1 and BRCA2 genes both encode proteins involved in the repair of DNA double strand breaks . While BRCA2 is mainly involved in homology-directed recombinational repair, BRCA1 may serve as a regulatory platform more upstream in assisting the signalling of breaks and the choice of repair pathways. BRCA1 is also involved in the transcriptional regulation of the estrogen and progesterone receptors. BRCA1 mutated breast cancers are usually estrogen-receptor negative and have a basal phenotype , while BRCA2 mutated tumours exhibit a broader spectrum of phenotypes.
BRCA1 and BRCA2 mutations are usually truncating, although pathogenic missense mutations have also been described in crucial functional domains such as the BRCA1 RING domain. There seems to be allele-specific expressivity as some of the mutations appear to confer higher risks for ovarian cancer than others, and ovarian cluster regions have been defined for both genes [68–70]. It has also been noted that not all mutations in BRCA1 and BRCA2 are highly penetrant for breast or ovarian cancer. Variants such as p.R1699Q in BRCA1 or p.K3326X in BRCA2 seem to be associated with rather low, though significant, breast cancer risks [71, 72]. This indicates that, although BRCA1 and BRCA2 are often referred to as “high-penetrance genes”, their mutational heterogeneity may produce a more diverse spectrum of allelic effects.
- PALB2: Subsequently, the “partner and localiser of BRCA2”, PALB2, has been identified as another breast cancer susceptibility gene [73, 74]. The PALB2 protein bridges BRCA1 and BRCA2 and synergizes in their function in recombinational DNA repair. Mutations in PALB2 predispose to breast cancer and gastric cancer, and the penetrance for breast cancer in Finnish multiple-case families has been found similarly high as for BRCA2 mutations . There is less evidence that PALB2 mutations predispose to ovarian cancer, although founder mutations have been identified in ovarian cancer patients from Poland and Russia [75, 76]. Another founder mutation in PALB2 is recurrent in British and Australian breast cancer patients, including multiple-case families . Altogether, PALB2 emerges as a third important breast cancer susceptibility gene with moderate- to high penetrance mutations for breast cancer.
UIMC1/ FAM175A/ BABAM1: The binding of BRCA1 to ubiquitylated and sumoylated histones at the site of double strand breaks is mediated by the ubiquitin-interaction motif containing protein UIMC1 (better known as RAP80) through binding the FAM175A gene product ABRAXAS (also known as ABRA1 or CCDC98) that interacts with BRCA1 in a complex stabilised by MERIT40, the product of the BABAM1 gene . Only few studies have addressed the role of UIMC1 or FAM175A mutations in breast cancer susceptibility. Familial breast cancer screening has revealed a rare alteration in the RAP80 UIM domain that impairs DNA damage response function , and an ABRAXAS mutation that disrupts nuclear localisation has been observed in breast cancer patients with mainly lobular tumour histology . In addition, BABAM1 has emerged as a significant low-penetrance risk locus for triple-negative breast cancer in genome-wide association studies as will be discussed further below.
- RAD51 paralogs: The fact that BRCA1, BRCA2 and PALB2 function together in the homology-directed recombinational repair of DNA double-strand breaks has soon prompted further investigation of candidate genes in this biological pathway. RAD51 is a key protein that mediates homologous recombination but apart from rare missense variants with uncertain significance, there have been no clearly pathogenic mutations in the coding region of the RAD51 proto-oncogene . However, a regulatory variant 135G/C in the RAD51 promoter acts as a genetic modifier of BRCA2 mutations . Similarly, low-penetrance variants at the RAD51L1 locus (also known as RAD51B) have recently been associated with breast cancer (see further below). Mutation analyses in further genes of RAD51 paralogs have uncovered RAD51C and RAD51D as susceptibility genes in hereditary breast and ovarian cancer families [29–31]. The initial data indicated that these mutations were specifically associated with a family history of ovarian cancer and were not overrepresented in breast cancer patients outside of ovarian cancer families [29–32]. However, mutations in RAD51C and RAD51D are collectively very rare and their risk pattern and tumour spectrum remains to be fully explored. Additional components of homologous recombinational repair complexes include RAD52, RAD54, XRCC2 and XRCC3. The RAD52 gene harbours two polymorphic stop codons which did not appear to confer a largely increased breast cancer risk, although minor risks have not been excluded [79, 80]. A single missense variant but no clearly pathogenic mutation has been reported in RAD54. A potentially disease-causing mutation has been found in XRCC2 in a recent exome sequencing study of British breast cancer patients . However, follow-up studies in other European populations did not detect XRCC2 mutations indicating that these are very rare . Altogether, mutations in RAD51 paralogs appear to exist at a low level in breast cancer but their contribution is small in most, if not all populations.
- Additional Fanconi Anemia genes: Homology-directed recombinational repair complexes are a conserved repair platform that are shared by at least two convergent signalling pathways, the ATM-mediated signalling pathway triggered by DNA double-strand breaks, and the Fanconi Anemia protein pathway triggered by interstrand crosslinks. Since it had been found that some breast and ovarian cancer susceptibility alleles, e.g. in BRCA2 (the FANCD1 gene), PALB2 (the FANCN gene) or RAD51C (the FANCO gene), cause Fanconi Anemia (FA) in the homozygous state, it has been reasonable to assess further FA genes for their role in breast and ovarian cancer. So far, mutations of the BRIP1 gene have been associated with FA in the biallelic state and with breast cancer in the monoallelic state, although the risk for breast cancer appears moderate . The BRIP1 protein, also known as FANCJ or BACH1, acts as a BRCA1- associated helicase, and mutations of BRIP1 also predispose to ovarian cancer with apparently higher penetrance . There is less evidence implicating the FA core proteins in breast cancer  but exome sequencing did uncover truncating mutations of FANCC and of FANCM in single studies [47, 49] and rare truncating mutations have also been observed in SLX4 (the FANCP gene) [50, 51, 84] suggesting that more FA genes might harbour rare breast cancer susceptibility alleles at a very low frequency. Their penetrance is unknown, however, the difficulties to confirm very early reports of an increased breast cancer risk in obligate heterozygotes from FA families may indicate that the risks are genetically heterogeneous and moderate on average, with a possible preponderance of FANCC.
- ATM: It has been known for long that blood relatives of patients with the neurodegenerative disorder Ataxia-Telangiectasia (A-T) face an increased breast cancer risk . Homozygous A-T patients usually do not survive into late adulthood, but a few females with attenuated A-T have been reported to develop bilateral breast cancer . The gene mutated in Ataxia-Telangiectasia, ATM, encodes a master protein kinase that orchestrates the cellular response to DNA double-strand breaks and controls via phosphorylation hundreds of proteins involved in cell cycle control, repair and apoptosis, among them BRCA1, BRCA2, BLM, TP53, CHEK2 and many other tumour suppressors . Truncating mutations in ATM appear to confer an about three-fold increased breast cancer risk to heterozygous carriers [37–39], and heterozygotes may account for 0 · 5-1% of most populations.
- MRE11A/ RAD50/ NBN: At the early steps of DNA double strand break signalling, chromosome breaks are sensed and the ATM protein is activated via the MRN complex consisting of the proteins MRE11A, RAD50, and NBN . The NBN gene underlies Nijmegen Breakage Syndrome (NBS), which is most prevalent in Eastern Europe due to a Slavic founder mutation . While biallelic mutations cause NBS, a cancer-prone developmental condition with early mortality, heterozygous carriers face an about 3–5 fold increased breast cancer risk [41–43]. Similarly, biallelic mutations in RAD50 give rise to a NBS-like disorder whereas heterozygotes for a Finnish founder mutation are predisposed towards breast cancer [44, 87]. MRE11A also is a gene for an A-T like disorder though there has been only one study to associate MRE11A mutations with breast cancer so far [40, 88]. Germ-line mutations in either of the three genes were also identified in an ovarian cancer sequencing study . Thus, similar to the Fanconi anemia proteins, several components of DNA double strand break sensing complexes seem to be target of germ-line mutations in breast and ovarian cancer susceptibility.
BLM: Another such gene that has recently been implicated in breast cancer susceptibility, is BLM, the gene mutated in Bloom’s Syndrome . Bloom’s Syndrome (BS) is an autosomal recessive syndrome associated with short stature, premature aging and a high propensity to develop malignancies including breast cancer . Cells from BS patients exhibit enhanced levels of sister chromatid exchanges, which reflects a hyperrecombinational phenotype as a consequence of BLM mutations and dysfunction of the encoded RecQ-type DNA helicase. A nonsense mutation in BLM, initially been observed in few BS patients, has been associated with breast cancer in Slavic populations, and the presently available evidence for BS mutations indicates an approximately 2–5 fold increase in breast cancer risk for heterozygotes [45, 46, 91].
- CHEK2: One of the major targets of the ATM kinase is CHEK2 which itself phosphorylates further tumour suppressor proteins, including p53 and BRCA1, in response to DNA damage . CHEK2 had initially been found mutated in Li-Fraumeni patients and one of these mutations, c.1100delC, has subsequently been associated with familial breast cancer [53, 54]. Heterozygous carriers have been reported with a 2–3 fold increase in breast cancer risk, with rare homozygotes being found at a much higher risk [55, 56]. In Eastern Europe, two further truncating mutations have been associated with at least similarly high breast cancer risks, whereas a missense mutation, p.I157T, has a lower penetrance [41, 57, 58]. There has also been some evidence for an association of CHEK2 mutations with ovarian cancer and for additional malignancies suggesting a more general role in cancer predisposition [89, 93]. It is interesting to note that, although CHEK2 interacts with BRCA1 in the same pathway, its mutations are significantly associated with estrogen receptor positive breast tumours, indicating an impact on tumour etiology that is different from BRCA1.
- PPM1D: Large-scale sequencing has identified truncating mutations in the p53-inducible protein phosphatase PPM1D which were specifically associated with breast cancer and ovarian cancer . PPM1D encodes the oncogenic phosphatase WIP1 that antagonizes ATM-mediated p53 phosphorylation. By contrast with the other genes discussed above, all of the identified PPM1D mutations were mosaic in lymphocyte DNA and, where tested, were not observed in breast or ovarian tissue, suggesting a late origin in the germ-line. Their mechanism of action in breast or ovarian cancer development is presently unknown. Somatic mosaicism has previously been observed for TP53 mutations outside of Li-Fraumeni families  suggesting that, in addition to classical heritable genetic factors, mosaic mutations may also contribute to the genetic predisposition to breast and ovarian cancer. These observations, if confirmed, could have important consequences for mutational screening as well as counselling. Certainly, the origin and frequency of mosaic mutations need to be studied in more detail before final conclusions can be derived.
Polymorphic variants with low penetrance:
Beyond the genes with relatively rare mutations discussed above, common polymorphisms have been predicted to significantly impact on risk and prevention if breast cancer were regarded as a polygenic disease . Several polymorphic loci are meanwhile known which influence the risk of breast cancer (Table 2). This has been mainly achieved through genome-wide association studies (GWAS) of single nucleotide polymorphism by large consortia during the past six years. The published GWAS efforts have uncovered over 70 genomic loci for breast cancer at a genome-wide significance level [72, 95–118]. All these loci harbour low-penetrance alleles with allelic odds ratios less than 1 · 5. Apart from a coding variant in DCLRE1B (the gene for the SNM1B/Apollo protein involved in DNA cross-link repair) and synonymous variants in BABAM1 and TERT, the majority of identified variants are either intronic or intergenic. The observed intronic and intergenic variants may affect genomic regions important for the regulation of gene expression and/or gene function. As these loci still explain only a small part of the heritable fraction, it is likely that the numbers will increase rapidly. Presently known GWAS loci now cover approximately 15% of the familial relative risk, compared to about 21% captured by moderate- to high penetrance alleles. But evidence suggests that several hundreds of low-penetrance breast cancer loci might exist, meaning that even with the numbers reached so far, studies have merely grazed the surface of the iceberg .
Many of the identified GWAS loci appear to be specific for breast carcinomas. For example, the gene for fibroblast growth factor receptor 2, FGFR2, harbours variants associated with breast but not ovarian cancer [95, 96] and breast cancer-associated variants in this gene appear to regulate the transcriptional activation of FGFR2 in an estrogen-dependent manner . The interaction with estrogen signalling may also explain why the association of some variants is restricted to ER-positive breast carcinomas (Table 2). Several of the GWAS loci further modify the risk for BRCA1 or BRCA2 mutation carriers . In some instances, variants have been observed to differentially associate with breast cancer risk in BRCA1 or BRCA2 carriers, and one variant has been reported to specifically associate with BRCA2 mutations . Additionally, variants at the RAD51L1 and TOX3 loci have independently been identified in a GWAS for male breast cancer .
A minor group of common susceptibility loci has turned out to be relevant for other common cancers as well, perhaps due to their general relevance for genome integrity . Some loci appear to influence both breast and ovarian cancer risk such as BABAM1, TERT, and the protooncogene MYC on chromosome 8q24. Variants at the BABAM1 locus, encoding a BRCA1 binding partner also known as MERIT40, have been specifically associated with triple-negative breast cancer and serous epithelial ovarian cancer, which resembles the picture seen with BRCA1 mutations [102, 134]. A closer inspection of the TERT locus, encoding a component of telomerase, has uncovered three independent regions of strong association with breast or ovarian cancer that only partially overlap and appear to act through different mechanisms of transcriptional regulation or splicing, respectively . Similarly, a closer inspection of the 8q24 locus upstream of MYC has indicated that the associations with different cancers were caused by independent variants at the same locus, possibly explained by tissue-specific regulation of gene expression through long-distance effects of enhancer regions . These findings illustrate that, in several instances, low-penetrance breast cancer susceptibility alleles may exert regulatory roles in the fine-tuning of gene expression in the respective tissue, and the patterns of regulation can be complex.
As a caveat, a GWAS roughly localises but usually does not yet identify the causal variant. In several cases there is more than one candidate gene in the region spanned by the associated LD block, and there can be even more candidate genes under putative regulatory control of the identified locus. For example at the 5q11.2 locus, the MAP3K1 gene represents an excellent candidate as it represents one of the most frequently mutated genes in breast tumours but MIER3 is another mammary tumour suppressor gene nearby [136, 137]. In some instances, available microarray data supported an association of the identified SNP with gene expression [72, 138]. One locus, LSP1, lies in proximity to the imprinted region H19/IGF2, and breast cancer risk has been reported to be limited to the paternally inherited allele . In other instances, identified loci have independently been correlated with previously known risk factors for breast cancer, such as FTO for obesity, INHBB for breast size or ZNF365 for mammographic density, strongly suggesting that the risk for breast cancer could be mediated via these physiological traits [139–142]. But for the majority of loci, fine-mapping approaches in different ethnic populations as well as gene expression and chromatin configuration studies are presently being used to further trace down the true predisposing variants. A combination of such approaches has recently identified regulatory mechanisms that underlie the association of independent variants at 11q13 with breast cancer and act in concert to orchestrate cyclin D1 expression .
Copy number variants (CNVs) have also been investigated at a genome-wide level. While one GWAS did not detect a significant association for breast cancer in European patients another one detected a significant association with a common APOBEC3B deletion in Chinese breast cancer patients [130, 143]. APOBEC3B encodes a cytosine deaminase that functions in localised hypermutation (“kataegis”) and may be responsible for chronic DNA damage in breast cancers [144, 145]. Loss of one or both APOBEC3B copies was associated with odds ratios of 1 · 31 and 1 · 76, respectively . Additional recent studies also showed a consistent increase in the frequency of rare CNVs in breast cancer cases when compared to controls [146, 147], with a particular enrichment of CNVs in genes involved in estrogen signalling and DNA double strand break repair in one study . If confirmed, this mirrors some results from genome-wide SNP analyses, although there has been no overlap of the identified loci thus far.
Implications for risk prediction and therapy
Hereditary breast cancer represents a challenge in terms of genetic counselling as well as preventive and therapeutic decisions. The identification of mutations in individuals from multiple-case families with breast cancer makes it possible to predict the age-dependent risk for different cancers, including recurrence risks in the already affected, and to counsel patient and blood relatives more appropriately. With the identification of modifying variants, the risk prediction for BRCA1 or BRCA2 mutation carriers can be further refined. Risk prediction may lead to an increased surveillance or targeted prevention including magnetic resonance imaging, medication (such as tamoxifen) or preventive surgery (such as prophylactic oophorectomy). In many countries, this is available to patients with a high (over 30%) lifetime risk such as BRCA1 or BRCA2 mutation carriers, whereas a more restrained position is taken for patients with intermediate-penetrance mutations conferring an about 3-fold increase in breast cancer risk such as ATM or CHEK2. Although the female carriers for those mutations could also benefit from increased surveillance, large studies on the efficacy of such measures are lacking. No further counselling is provided for patients carrying common risk alleles at polymorphic loci, as these risks are too small individually to be clinically meaningful. This situation may change, however, if one considers cumulative effects for several of those variants that can reach substantial risk modifications already at the present stage of knowledge. Previous estimates predicted that half of the population at highest risk may account for about 88% of breast cancer cases . Using the current set of loci and assuming that all loci combine multiplicatively, risks of breast cancer were estimated approximately 2 · 3-fold and 3-fold higher for individuals in the top 5% and 1% of the population, relative to the population average . With the identification of many more low-risk loci it may become possible to calculate combinatorial risks that could be useful in a stratified approach of cancer prevention in the future [148–150].
Population diversity needs to be taken into account for breast cancer susceptibility at all levels of penetrance. Due to founder effects, single mutations can contribute significantly to the breast cancer burden in founder populations and intermediate-risk alleles in some genes have almost exclusively been found in certain population groups, such as for FAM175A and RAD50 in the Finnish population or NBN in Slavic populations [28, 41–44]. In fact, much of the present knowledge about those genes relies on particular founder mutations, and in regard of allelic heterogeneity one must be cautious to extrapolate and generalise these observations to other less common alleles. Similarly, common polymorphisms at breast cancer susceptibility loci will differentially impact on breast cancer risk in different ethnic groups, if they display different frequencies or different linkage disequilibrium patterns across populations, such as CASP8*D302H that is virtually absent in Asians , or the ESR1 locus at which different risk alleles SNPs have emerged in Asians and Europeans [100, 103, 125–127]. Gene-based strategies for an improved risk prediction will therefore need to be elaborated in a population-specific way.
In addition to risk prediction, identifying the genetic basis of breast cancer in the individual patient might have further prognostic and therapeutic implications. Breast cancer therapy has been guided for long by the presence or absence of gene products such as hormone receptors or HER2/neu. These tumour characteristics are partly determined by germ-line mutations, as exemplified by BRCA1 mutations which are frequently associated with triple-negative breast cancers, but breast cancer pathology also seems to be influenced by low-penetrance variants like those in FGFR2 that are strongly correlated with estrogen-receptor positive disease [95, 96, 151]. In fact, many of the hitherto identified variants appear to preferentially associate with a defined estrogen receptor status (Table 2) [119, 123, 152]. Further studies are presently underway to investigate whether SNP profiling could be of prognostic value .
The identification of breast cancer susceptibility alleles may also guide the development of new drugs that target additional breast cancer pathways, such as oncogenic signalling mediated by FGF receptors  or mutation accumulation mediated through ABOBEC3B. Such new drugs are particularly needed in the treatment of otherwise poorly targetable breast carcinomas such as triple-negative tumours  and the identification of risk alleles in genes like BABAM1 or MDM4 in this particular subgroup may offer promising avenues for new therapeutic regimens. The concept of “synthetic lethality” as exemplified by the introduction of PARP1 inhibitors into treatment of patients with BRCA1 or BRCA2 mutations may also prove useful in the development of other compounds to target additional genetic predispositions [156–158].
Conclusions and outlook
Tremendous progress has been made during the past few years in deciphering the polygenic susceptibility to breast cancer. The results suggest that key pathways are targeted by different sources of genetic variation influencing the hereditary risk. To a large extent these findings fulfil the predictions made some forty years ago that “genes may either cause susceptibility of the mammary gland to hormonal action [or to a virus], or induce an easy transformation from a normal to a malignant cell” . It can be anticipated that hundreds of additional loci are still to be detected that collectively form the basic layout for an individual’s susceptibility to breast cancer. With many more genes being identified, a deeper understanding of breast cancer development and progression together with the ability of gene-based stratification should ultimately lead to improved prevention and an individually tailored therapy to the benefit of each patient.
