  1. 26 different MSH6 mutations have been detected in our patient cohort. Not previously reported = not reported in the Leiden Open Variation Database (LOVD), the Mismatch Repair Genes Variant Database (Memorial University of Newfoundland) or the InSIGHT database as a HNPCC/Lynch syndrome mutation. DB-ID = Database identification number from LOVD.
  2. #-ve = loss of protein expression, +ve = protein expression present
  3. *Submitted to LOVD by our research group
