Genes affected
ENTPD1 (HGNC:3363): (ectonucleoside triphosphate diphosphohydrolase 1) The protein encoded by this gene is a plasma membrane protein that hydrolyzes extracellular ATP and ADP to AMP. Inhibition of this protein's activity may confer anticancer benefits. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2015]
ENTPD1-AS1 (HGNC:45203): (ENTPD1 antisense RNA 1)

This variant has not been reported in the literature in individuals affected with ENTPD1-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.0009%). This sequence change replaces leucine, which is neutral and non-polar, with phenylalanine, which is neutral and non-polar, at codon 350 of the ENTPD1 protein (p.Leu350Phe). ClinVar contains an entry for this variant (Variation ID: 541702). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on ENTPD1 protein function.
