ROR2 and familial dilated cardiomyopathy: If this higher RA:PCWP cut off were used, 2 (22%) of ICM-RVF and 11 (42%) of DCM-RVF would meet this criterion, which is comparable to the portion of RVF patients meeting the NF 95th percentile for ROR2 protein expression (11 and 35%, respectively for ICM-RVF and DCM-RVF).
