Color Diagnostics, LLC DBA Color Health RCV001183305 SCV001349000 uncertain significance Cardiomyopathy 2023-12-05 criteria provided, single submitter clinical testing This missense variant replaces glutamic acid with lysine at codon 754 of the DSP protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with cardiovascular disorders in the literature. This variant has been identified in 4/282654 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance.

Ambry Genetics RCV002444649 SCV002733387 uncertain significance Cardiovascular phenotype 2020-01-03 criteria provided, single submitter clinical testing The p.E754K variant (also known as c.2260G>A), located in coding exon 16 of the DSP gene, results from a G to A substitution at nucleotide position 2260. The glutamic acid at codon 754 is replaced by lysine, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
