DSC2 non-truncating variants in ARVC cohorts


The table below lists the 7 rare (MAF<0.0001 in ExAC) non-truncating DSC2 variants identified in a cohort of 351 ARVC patients. When this rare variant frequency of 0.01994 is compared with a background population rate of 0.00938, there is a case excess of 0.01056, although this is not statistically significant for non-truncating DSC2 variants in ARVC (p=0.0504).
