Comment:

This missense variant replaces leucine with arginine at codon 13 of the DSG2 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with DSG2-related disorders in the literature. This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance.

Comment:

The c.38T>G (p.L13R) alteration is located in exon 1 (coding exon 1) of the DSG2 gene. This alteration results from a T to G substitution at nucleotide position 38, causing the leucine (L) at amino acid position 13 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
