Genes affected

ENTPD6 (HGNC:3368): (ectonucleoside triphosphate diphosphohydrolase 6) ENTPD6 is similar to E-type nucleotidases (NTPases). NTPases, such as CD39, mediate catabolism of extracellular nucleotides. ENTPD6 contains 4 apyrase-conserved regions which are characteristic of NTPases. Alternative splicing results in multiple transcript variants encoding different isoforms.

The c.1169C>T (p.A390V) alteration is located in exon 12 (coding exon 11) of the ENTPD6 gene. This alteration results from a C to T substitution at nucleotide position 1169, causing the alanine (A) at amino acid position 390 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
