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.

ENTPD3-AS1 (HGNC:):

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

ACMG classification

Our verdict: Likely_pathogenic. The variant received 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.977
