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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 13, 2023The c.892G>A (p.G298R) alteration is located in exon 10 (coding exon 9) of the ENTPD6 gene. This alteration results from a G to A substitution at nucleotide position 892, causing the glycine (G) at amino acid position 298 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
