DSP non-truncating variants in DCM cohorts


The table below lists the 14 rare (MAF<0.0001 in ExAC) non-truncating DSP variants identified in a cohort of 304 DCM patients. When this rare variant frequency of 0.04605 is compared with a background population rate of 0.03078, there is a case excess of 0.01527, although this is not statistically significant for non-truncating DSP variants in DCM (p=0.0660).
