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.573C>G (p.N191K) alteration is located in exon 6 (coding exon 5) of the ENTPD3 gene. This alteration results from a C to G substitution at nucleotide position 573, causing the asparagine (N) at amino acid position 191 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
