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.
