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]

For these reasons, this variant has been classified as Pathogenic. Experimental studies have shown that this missense change affects AGXT function (PMID: 17495019, 22923379, 24718375). 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. ClinVar contains an entry for this variant (Variation ID: 204126). This missense change has been observed in individual(s) with Primary Hyperoxaluria Type 1 (PMID: 15849466, 17495019). This variant is present in population databases (rs180177264, gnomAD 0.0009%). This sequence change replaces cysteine, which is neutral and slightly polar, with arginine, which is basic and polar, at codon 253 of the AGXT protein (p.Cys253Arg). -
