The table below lists the 8 rare (MAF<0.0001 in ExAC) protein-altering JUP variants identified in a cohort of 94 ARVC patients. When this rare variant frequency of 0.08511 is compared with a background population rate of 0.01196, there is a statistically significant case excess of 0.07315 (p<0.0001), which suggests that approximately 7 of these variants may be pathogenic.
