GeneDx RCV000488957 SCV000577633 likely pathogenic not provided 2015-09-01 criteria provided, single submitter clinical testing The E1261X likely pathogenic variant in the MYBPC3 gene has not been reported as a disease-causing variant or as a benign polymorphism to our knowledge. E1261X is predicted to cause loss of normal protein function by protein truncation, however the effect of deleting fourteen C-terminal amino acids is unknown. Other nonsense variants in the MYBPC3 gene have been reported in the Human Gene Mutation Database in association with cardiomyopathy (Stenson P et al., 2014), however only one is located downstream of E1261X. The E1261X variant was not observed in approximately 6,200 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations.Therefore, this variant is a strong candidate for a pathogenic variant, however the possibility that it is a benign variant cannot be excluded
