Genes affected

ENTPD1 (HGNC:3363): (ectonucleoside triphosphate diphosphohydrolase 1) The protein encoded by this gene is a plasma membrane protein that hydrolyzes extracellular ATP and ADP to AMP. Inhibition of this protein's activity may confer anticancer benefits. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2015]
