Genes affected

AGXT (HGNC:341): (alanine--glyoxylate aminotransferase) This gene is expressed only in the liver and the encoded protein is localized mostly in the peroxisomes, where it is involved in glyoxylate detoxification. Mutations in this gene, some of which alter subcellular targetting, have been associated with type I primary hyperoxaluria. [provided by RefSeq, Jul 2008]

This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 47 of the AGXT protein (p.Gly47Arg). This variant is present in population databases (rs180177173, gnomAD 0.02%). This missense change has been observed in individual(s) with type 1 primary hyperoxaluria (PMID: 17460142, 20564000). ClinVar contains an entry for this variant (Variation ID: 204076). 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 AGXT protein function with a positive predictive value of 80%. Experimental studies have shown that this missense change affects AGXT function (PMID: 24718375, 26149463). For these reasons, this variant has been classified as Pathogenic. -
