The table below lists the 22 rare (MAF<0.0001 in ExAC) non-truncating DSP variants identified in a cohort of 352 ARVC patients. When this rare variant frequency of 0.06250 is compared with a background population rate of 0.03078, there is a statistically significant case excess of 0.03172 (p=0.0018), which suggests that approximately 11 of these variants may be pathogenic.
