CSRP3 non-truncating variants in HCM cohorts


The table below lists the 2 rare (MAF<0.0001 in ExAC) non-truncating CSRP3 variants identified in a cohort of 1535 HCM patients. As the background population rate of rare non-truncating CSRP3 variants (0.00288) is greater than this case frequency (0.00130), there is no excess of variants in this HCM patient cohort, suggesting that non-truncating CSRP3 variants are not causative for HCM.
