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 29, 2022The c.386C>T (p.T129M) alteration is located in exon 4 (coding exon 3) of the ENTPD6 gene. This alteration results from a C to T substitution at nucleotide position 386, causing the threonine (T) at amino acid position 129 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
