Laboratory for Molecular Medicine,Partners HealthCare Personalized Medicine RCV000615030 SCV000710899 uncertain significance not specified 2017-03-03 criteria provided, single submitter clinical testing Variant classified as Uncertain Significance - Favor Benign. The p.Arg199Lys var iant in DSP has not been previously reported in individuals with cardiomyopathy, but has been identified in 3/10388 African chromosomes by the Exome Aggregation Consortium (ExAC,; dbSNP rs143648545). Arginine (Arg) at position 199 is not conserved in evolutionarily distant species, with > 20 species carrying a lysine (Lys) at this position, raising the possibility tha t a change at this position may be tolerated. Additional computational predictio n tools suggest that the p.Arg199Lys variant may not impact the protein, though this information is not predictive enough to rule out pathogenicity. In summary, while the clinical significance of the p.Arg199Lys variant is uncertain, its pr esence in non-mammals suggests that it is more likely to be benign.
