The table below lists the 1 rare (MAF<0.0001 in ExAC) truncating MYL2 variants identified in a cohort of 1535 HCM patients. When this rare variant frequency of 0.00065 is compared with a background population rate of 0.00024, there is a case excess of 0.00041, although this is not statistically significant for truncating MYL2 variants in HCM (p=0.0932).
