Genes affected

ENTPD3 (HGNC:3365): (ectonucleoside triphosphate diphosphohydrolase 3) This gene encodes a plasma membrane-bound divalent cation-dependent E-type nucleotidase. The encoded protein is involved in the regulation of extracellular levels of ATP by hydrolysis of it and other nucleotides. Multiple transcript variants have been described.

EIF1B-AS1 (HGNC:):

ENTPD3-AS1 (HGNC:26710): (ENTPD3 antisense RNA 1)

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.86).
