Description

The p.W10C variant (also known as c.30G>T), located in coding exon 1 of the DSC2 gene, results from a G to T substitution at nucleotide position 30. The tryptophan at codon 10 is replaced by cysteine, an amino acid with highly dissimilar properties. This variant was not reported in population based cohorts in the following databases: Database of Single Nucleotide Polymorphisms (dbSNP), NHLBI Exome Sequencing Project (ESP), and 1000 Genomes Project. In the ESP, this variant was not observed in 3073 samples (6146 alleles) with coverage at this position. This amino acid position is poorly 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.
