Description

The p.R265K variant (also known as c.794G>A), located in coding exon 7 of the DSP gene, results from a G to A substitution at nucleotide position 794. The arginine at codon 265 is replaced by lysine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
