  1. A Acceptor, D Donor, NE No effect
  2. aThe variant is considered as deleterious by six of the six protein function prediction or three of the five splice-site prediction algorithms for coding or noncoding variants, respectively
  3. b > 20% change in score (i.e., a wild-type splice-site score decreases and/or a cryptic splice-site score increases) is considered significant
  4. cCanonical splice acceptor site is abolished (MaxEntScan score + 2.46 → -5.49) and creates a cryptic splice acceptor site at c.877
