Effect in Cardiac Disease

This variant is considered a rare variant, with a population frequency of 0.00002489 (ExAC mean allelic frequency).

HCM

Rare MYBPC3 Non-Truncating variants are significantly enriched in HCM (details) and have an etiological fraction (EF) of 0.82.

OMGL: Detected in 0 / 3267 HCM patients.

LMM:   Detected in 0 / 2912 HCM patients.

DCM

There is no significant excess of rare MYBPC3 Non-Truncating variants in DCM (details).

OMGL: Detected in 0 / 405 DCM patients.

LMM:   Detected in 0 / 756 DCM patients.

The EF is the estimated proportion of rare variants of this class that will be pathogenic in a cardiomyopathy proband, a prior probability based solely on variant frequency data in cases and controls, and should be further refined by additional evidence such as family segregation data, known association with disease, population frequency, protein domain analysis, functional studies and in silico algorithms to assess the significance of a variant.
