MYBPC3 variants in HCM cohorts

The table below lists the 540 rare (MAF<0.0001 in ExAC) protein-altering MYBPC3 variants identified in a cohort of 2912 HCM patients. When this rare variant frequency of 0.18544 is compared with a background population rate of 0.01970, there is a statistically significant case excess of 0.16574 (p<0.0001), which suggests that approximately 481 of these variants may be pathogenic.

Variant Type: All protein-altering variants - Truncating variants - Non-Truncating variants
