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]

The missense variant p.G350D in AGXT (NM_000030.3) has been reported previously in multiple affected indviduals (Du DF et al; Rao NM et al). The variant was submitted to ClinVar as Likely Pathogenic. The p.G350D variant is observed in 11/30,610 (0.0359%) alleles from individuals of South Asian background in gnomAD Exomes and is novel (not in any individuals) in 1000 Genomes. There is a moderate physicochemical difference between glycine and aspartic acid. The p.G350D missense variant is predicted to be damaging by both SIFT and PolyPhen2. The glycine residue at codon 350 of AGXT is conserved in all mammalian species. The nucleotide c.1049 in AGXT is predicted conserved by GERP++ and PhyloP across 100 vertebrates. For these reasons, this variant has been classified as Likely Pathogenic. -

This sequence change replaces glycine, which is neutral and non-polar, with aspartic acid, which is acidic and polar, at codon 350 of the AGXT protein (p.Gly350Asp). This variant is present in population databases (rs180177156, gnomAD 0.03%). This missense change has been observed in individual(s) with hyperoxaluria (PMID: 9604803, 23551880, 30341509, 35149915). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This variant is also known as G1171A. ClinVar contains an entry for this variant (Variation ID: 188986). 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. Experimental studies have shown that this missense change affects AGXT function (PMID: 22018727, 22923379, 30341509). For these reasons, this variant has been classified as Pathogenic. -
