Description

This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 835 of the DSG2 protein (p.Thr835Met). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with DSG2-related conditions. ClinVar contains an entry for this variant (Variation ID: 972598). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
