Genes affected
MYBPC3 (HGNC:7551): (myosin binding protein C3) MYBPC3 encodes the cardiac isoform of myosin-binding protein C. Myosin-binding protein C is a myosin-associated protein found in the cross-bridge-bearing zone (C region) of A bands in striated muscle. MYBPC3 is expressed exclusively in heart muscle and is a key regulator of cardiac contraction. Mutations in this gene are a frequent cause of familial hypertrophic cardiomyopathy.

Benign, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpNov 16, 2020Variant summary: MYBPC3 c.3106C>T (p.Arg1036Cys) results in a non-conservative amino acid change located in the Immunoglobulin-like domain of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.00042 in 245430 control chromosomes, predominantly at a frequency of 0.0056 within the African or African-American subpopulation in the gnomAD database. The observed variant frequency within African or African-American control individuals in the gnomAD database is approximately 6 fold of the estimated maximal expected allele frequency for a pathogenic variant in MYBPC3 causing Cardiomyopathy phenotype (0.001), strongly suggesting that the variant is a benign polymorphism found primarily in populations of African or African-American origin. c.3106C>T has been reported in the literature in individuals affected with Cardiomyopathy. These reports do not provide unequivocal conclusions about association of the variant with Cardiomyopathy. Ten clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as benign/likely benign. Based on the evidence outlined above, the variant was classified as benign. -
