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]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -9 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.03844744).

BS1

Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.000571 (87/152322) while in subpopulation NFE AF= 0.00104 (71/68028). AF 95% confidence interval is 0.000848. There are 1 homozygotes in gnomad4. There are 34 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Hereditary spastic paraplegia 64

Uncertain:1Other:1

Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Sep 12, 2022	This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 9 of the ENTPD1 protein (p.Val9Met). This variant is present in population databases (rs150772804, gnomAD 0.09%), and has an allele count higher than expected for a pathogenic variant. This variant has not been reported in the literature in individuals affected with ENTPD1-related conditions. ClinVar contains an entry for this variant (Variation ID: 374088). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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. -
not provided, no classification provided	phenotyping only	GenomeConnect - Invitae Patient Insights Network	-	Variant interpreted as Uncertain significance and reported on 03-29-2019 by Lab Invitae. GenomeConnect-Invitae Patient Insights Network assertions are reported exactly as they appear on the patient-provided report from the testing laboratory. Registry team members make no attempt to reinterpret the clinical significance of the variant. Phenotypic details are available under supporting information. -
