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 phenylalanine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 152 of the AGXT protein (p.Phe152Ile). This variant is present in population databases (rs121908524, gnomAD 0.02%). This missense change has been observed in individual(s) with hyperoxaluria (PMID: 8101040, 11708860, 25363903). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 5645). 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: 10960483). For these reasons, this variant has been classified as Pathogenic. -

Variant summary: AGXT c.454T>A (p.Phe152Ile) results in a non-conservative amino acid change located in the Aminotransferase class V domain (IPR000192) of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 7.6e-05 in 248758 control chromosomes (gnomAD). The variant, c.454T>A, has been reported in the literature in multiple individuals affected with Primary Hyperoxaluria Type 1 (van der Hoeven_2012, Monico_2007). These data indicate that the variant is very likely to be associated with disease. A ClinVar submission from a clinical diagnostic laboratory (evaluation after 2014) cites the variant as "pathogenic." Based on the evidence outlined above, the variant was classified as pathogenic. -
