The Ser658Cys variant in RBM20 has not been reported in the literature. It has b een identified by our laboratory in 1 Caucasian individual with DCM (LMM unpubli shed data), though it did not segregate with disease in an affected family membe r. The frequency of this variant in large European American and African American populations cannot be determined from the NHLBI Exome Sequencing Project (http: //evs.gs.washington.edu/EVS/) because coverage at this position was insufficient or unavailable. Serine (Ser) at position 658 is not conserved in mammals, thoug h additional computational analyses (biochemical amino acid properties, AlignGVG D, and SIFT) do not provide strong support for or against an impact to the prote in. Finally, this variant lies within exon 9, which encodes a conserved protein domain where other pathogenic variants have been reported (Brauch 2009, Li 2010) . In summary, additional studies are needed to fully assess the clinical signifi cance of the Ser658Cys variant. -
