Genes affected
NT5C3A (HGNC:17820): (5'-nucleotidase, cytosolic IIIA) This gene encodes a member of the 5'-nucleotidase family of enzymes that catalyze the dephosphorylation of nucleoside 5'-monophosphates. The encoded protein is the type 1 isozyme of pyrimidine 5' nucleotidase and catalyzes the dephosphorylation of pyrimidine 5' monophosphates. Mutations in this gene are a cause of hemolytic anemia due to uridine 5-prime monophosphate hydrolase deficiency. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene, and pseudogenes of this gene are located on the long arm of chromosomes 3 and 4.

This sequence change replaces aspartic acid, which is acidic and polar, with valine, which is neutral and non-polar, at codon 98 of the NT5C3A protein (p.Asp98Val). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. 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) performed at Invitae indicates that this missense variant is expected to disrupt NT5C3A protein function. ClinVar contains an entry for this variant (Variation ID: 4479). This missense change has been observed in individuals with pyrimidine 5'-nucleotidase deficiency (PMID: 11369620; Invitae). It has also been observed to segregate with disease in related individuals. This variant is present in population databases (rs104894025, gnomAD 0.007%). -
