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.

Ambry Genetics

Sep 16, 2021

The c.1159G>A (p.D387N) alteration is located in exon 12 (coding exon 11) of the ENTPD6 gene. This alteration results from a G to A substitution at nucleotide position 1159, causing the aspartic acid (D) at amino acid position 387 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
