Genes affected

DSP (HGNC:3052): (desmoplakin) This gene encodes a protein that anchors intermediate filaments to desmosomal plaques and forms an obligate component of functional desmosomes. Mutations in this gene are the cause of several cardiomyopathies and keratodermas, including skin fragility-woolly hair syndrome. Alternative splicing results in multiple transcript variants.

Ser2843_Arg2846del in exon 24 of DSP: This variant has not been reported in ind ividuals with cardiomyopathy or in large population studies and is not expected to have clinical significance. It was previously identified in 0.7% (61/8254) of European American chromosomes by the NHLBI Exome Sequencing Project; however, t hat data is no longer available (http://evs.gs.washington.edu/EVS/). This varian t was not identified in a cohort of 350 chromosomes of mixed race with ARVC; how ever, it was idenitified in 1/854 healthy, race-matched control chromosomes (Kap plinger 2011). This in-frame deletion of four amino acids occurs within a sectio n of repeating amino acids, which can result from several different DNA deletion s, and is present in at least three mammals (dolphin, opossum, and platypus) and other evolutionarily distant species. Although this data supports that the Ser2 843_Arg2846del variant may be benign, additional studies are needed to fully ass ess its clinical significance. -

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
