CSRP3 variants in HCM cohorts


The table below lists the 11 rare (MAF<0.0001 in ExAC) protein-altering CSRP3 variants identified in a cohort of 2167 HCM patients (1535 patients from OMGL, 632 patients from LMM). When this rare variant frequency of 0.00508 is compared with a background population rate of 0.00324, there is a case excess of 0.00184, although this is not statistically significant for protein-altering CSRP3 variants in HCM (p=0.1766).
