Description

The p.R1582M variant (also known as c.4745G>T), located in coding exon 23 of the DSP gene, results from a G to T substitution at nucleotide position 4745. The arginine at codon 1582 is replaced by methionine, an amino acid with similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
