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 -21 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.54).
BP6
Variant 11-47349870-C-A is Benign according to our data. Variant chr11-47349870-C-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 42772.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=-4.82 with no splicing effect.
BS1
Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.00036 (526/1459932) while in subpopulation SAS AF = 0.00587 (504/85906). AF 95% confidence interval is 0.00544. There are 5 homozygotes in GnomAdExome4. There are 374 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check.
BS2
High Homozygotes in GnomAdExome4 at 5 AR,AD gene
