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 P10A variant in the AGXT gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The P10A variant was not observed with any significant frequency in approximately 6500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. The P10A variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. This substitution occurs at a position that is conserved across species. However, in silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. Additionally, missense variants in nearby residues (T9N and P11R) have been reported in the Human Gene Mutation Database in association with PH1 (Stenson et al., 2014), supporting the functional importance of this region of the protein. We interpret P10A as a variant of uncertain significance. -
