Genes affected

AMPD2 (HGNC:469): (adenosine monophosphate deaminase 2) The protein encoded by this gene is important in purine metabolism by converting AMP to IMP. The encoded protein, which acts as a homotetramer, is one of three AMP deaminases found in mammals. Several transcript variants encoding different isoforms have been found for this gene.
