Genes affected
ENTPD2 (HGNC:3364): (ectonucleoside triphosphate diphosphohydrolase 2) The protein encoded by this gene is the type 2 enzyme of the ecto-nucleoside triphosphate diphosphohydrolase family (E-NTPDase). E-NTPDases are a family of ecto-nucleosidases that hydrolyze 5'-triphosphates. This ecto-ATPase is an integral membrane protein. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Jul 2008]

The c.1241G>A (p.G414D) alteration is located in exon 8 (coding exon 8) of the ENTPD2 gene. This alteration results from a G to A substitution at nucleotide position 1241, causing the glycine (G) at amino acid position 414 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
