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 GeneticsMar 25, 2024The c.230C>G (p.A77G) alteration is located in exon 3 (coding exon 2) of the ENTPD6 gene. This alteration results from a C to G substitution at nucleotide position 230, causing the alanine (A) at amino acid position 77 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
