Genes affected

UBE2T (HGNC:25009): (ubiquitin conjugating enzyme E2 T) The protein encoded by this gene catalyzes the covalent attachment of ubiquitin to protein substrates. Defects in this gene have been associated with Fanconi anemia of complementation group T. Two transcript variants encoding different isoforms have been found for this gene.

This sequence change replaces arginine, which is basic and polar, with glycine, which is neutral and non-polar, at codon 144 of the UBE2T protein (p.Arg144Gly). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with UBE2T-related conditions. 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. -
