Genes affected
ENTPD4 (HGNC:14573): (ectonucleoside triphosphate diphosphohydrolase 4) This gene encodes a member of the apyrase protein family. Apyrases are enzymes that catalyze the hydrolysis of nucleotide diphosphates and triphosphates in a calcium or magnesium-dependent manner. The encoded protein is an endo-apyrase and may play a role in salvaging nucleotides from lysosomes. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene, and these isoforms may differ in divalent cation dependence and substrate specificity.

The c.1717G>T (p.V573L) alteration is located in exon 1 (coding exon 1) of the ENTPD4 gene. This alteration results from a G to T substitution at nucleotide position 1717, causing the valine (V) at amino acid position 573 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
