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.

Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpSep 06, 2022This sequence change falls in intron 5 of the UBE2T gene. It does not directly change the encoded amino acid sequence of the UBE2T protein. It affects a nucleotide within the consensus splice site. This variant is present in population databases (rs747022602, gnomAD 0.09%), and has an allele count higher than expected for a pathogenic variant. This variant has not been reported in the literature in individuals affected with UBE2T-related conditions. Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. 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. -
