MYH7 non-truncating variants in HCM cohorts

The table below lists the 434 rare (MAF<0.0001 in ExAC) non-truncating MYH7 variants identified in a cohort of 3200 HCM patients. When this rare variant frequency of 0.13562 is compared with a background population rate of 0.01350, there is a statistically significant case excess of 0.12212 (p<0.0001), which suggests that approximately 391 of these variants may be pathogenic.

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