MYH7 variants in HCM cohorts


The table below lists the 438 rare (MAF<0.0001 in ExAC) protein-altering MYH7 variants identified in a cohort of 3200 HCM patients. When this rare variant frequency of 0.13687 is compared with a background population rate of 0.01398, there is a statistically significant case excess of 0.12289 (p<0.0001), which suggests that approximately 394 of these variants may be pathogenic.
