VCL variants in DCM cohorts

The table below lists the 13 rare (MAF<0.0001 in ExAC) protein-altering VCL variants identified in a cohort of 590 DCM patients. When this rare variant frequency of 0.02203 is compared with a background population rate of 0.01016, there is a case excess of 0.01187, although this is not statistically significant for protein-altering VCL variants in DCM (p=0.0111).
