MYH7 variants in DCM cohorts

The table below lists the 45 rare (MAF<0.0001 in ExAC) protein-altering MYH7 variants identified in a cohort of 756 DCM patients. When this rare variant frequency of 0.05952 is compared with a background population rate of 0.01398, there is a statistically significant case excess of 0.04554 (p<0.0001), which suggests that approximately 35 of these variants may be pathogenic.
