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.

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -16 ACMG points.

BP6

Variant 11-47331512-CT-C is Benign according to our data. Variant chr11-47331512-CT-C is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 304937.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.00114 (174/152352) while in subpopulation SAS AF = 0.0348 (168/4830). AF 95% confidence interval is 0.0305. There are 4 homozygotes in GnomAd4. There are 125 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 4 AR,AD gene
