The table below lists the 1 rare (MAF<0.0001 in ExAC) protein-altering MYL2 variants identified in a cohort of 188 DCM patients. When this rare variant frequency of 0.00532 is compared with a background population rate of 0.00176, there is a case excess of 0.00356, although this is not statistically significant for protein-altering MYL2 variants in DCM (p=0.5724).
