Description

The p.D1248N variant (also known as c.3742G>A), located in coding exon 23 of the DSP gene, results from a G to A substitution at nucleotide position 3742. The aspartic acid at codon 1248 is replaced by asparagine, an amino acid with highly similar properties. This amino acid position is well conserved in available vertebrate species. 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.
