Description

The p.T730A variant (also known as c.2188A>G), located in coding exon 14 of the DSG2 gene, results from an A to G substitution at nucleotide position 2188. The threonine at codon 730 is replaced by alanine, 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.
