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.

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -5 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.028956026).
BS1
Variant frequency is greater than expected in population eas. GnomAdExome4 allele frequency = 0.00000958 (14/1461818) while in subpopulation EAS AF = 0.000353 (14/39686). AF 95% confidence interval is 0.000213. There are 0 homozygotes in GnomAdExome4. There are 8 alleles in the male GnomAdExome4 subpopulation. Median coverage is 30. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

This sequence change replaces glycine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 170 of the UBE2T protein (p.Gly170Val). This variant is present in population databases (rs763798312, gnomAD 0.05%). This variant has not been reported in the literature in individuals affected with UBE2T-related conditions. ClinVar contains an entry for this variant (Variation ID: 1337447). 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 tolerated. 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. -
