DSC2 variants in ARVC cohorts

The table below lists the 9 rare (MAF<0.0001 in ExAC) protein-altering DSC2 variants identified in a cohort of 351 ARVC patients. When this rare variant frequency of 0.02564 is compared with a background population rate of 0.00964, there is a case excess of 0.01600, although this is not statistically significant for protein-altering DSC2 variants in ARVC (p=0.0080).
