This variant is considered a rare variant, with a population frequency of 0.00000829 (ExAC mean allelic frequency).
Rare TPM1 Non-Truncating variants are significantly enriched in HCM (details) and have an etiological fraction (EF) of 0.94.
OMGL: Detected in 0 / 1535 HCM patients.
LMM: Detected in 0 / 2912 HCM patients.
Rare TPM1 Non-Truncating variants are significantly enriched in DCM (details) and have an etiological fraction (EF) of 0.95.
OMGL: Detected in 0 / 355 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.

The Exome Aggregation Consortium (ExAC) is a database of 60,706 unrelated individuals sequenced as part of various disease-specific and population genetic studies. There is partial overlap between ExAC and 1000 Genomes (1KG) (1,851 of the 2,504 samples in 1KG) and the Exome Sequencing Project (ESP) (3,936 of the 6,500 samples in ESP).
