Genes affected

ENTPD3 (HGNC:3365): (ectonucleoside triphosphate diphosphohydrolase 3) This gene encodes a plasma membrane-bound divalent cation-dependent E-type nucleotidase. The encoded protein is involved in the regulation of extracellular levels of ATP by hydrolysis of it and other nucleotides. Multiple transcript variants have been described.

The c.616T>G (p.W206G) alteration is located in exon 7 (coding exon 6) of the ENTPD3 gene. This alteration results from a T to G substitution at nucleotide position 616, causing the tryptophan (W) at amino acid position 206 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
