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]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 0 ACMG points.

PM1

In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 2 benign, 4 uncertain in NM_000030.3

PM5

Other missense variant is known to change same aminoacid residue: Variant chr2-240868897-C-G is described in ClinVar as [Likely_pathogenic]. Clinvar id is 204069.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BP4

Computational evidence support a benign effect (MetaRNN=0.2520356).

BP6

Variant 2-240868897-C-A is Benign according to our data. Variant chr2-240868897-C-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 204018.We mark this variant Likely_benign, oryginal submissions are: {Uncertain_significance=2, Likely_benign=1}.

BS2

High Homozygotes in GnomAdExome4 at 3 AR geneVariant has number of homozygotes lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

Uncertain significance, no assertion criteria provided	in vitro	Clinical Biochemistry Laboratory, Health Services Laboratory	Nov 27, 2014	- -
Uncertain significance, criteria provided, single submitter	clinical testing	Illumina Laboratory Services, Illumina	Apr 28, 2017	This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -

PreventionGenetics, part of Exact Sciences

Sep 26, 2022

The AGXT c.32C>A variant is predicted to result in the amino acid substitution p.Pro11His. To our knowledge, this variant has not been reported in the literature. However, a different amino acid substitution affecting the same residue (p.Pro11Arg) has been reported to impact the catalytic activity of the AGT enzyme (Williams et al. 2009. PubMed ID: 19479957). The c.32C>A (p.Pro11His) variant is reported in 0.14% of alleles in individuals of East Asian descent in gnomAD, including 2 homozygotes (http://gnomad.broadinstitute.org/variant/2-241808314-C-A). While we suspect this variant is benign, at this time we interpret its clinical significance as uncertain due to the absence of conclusive functional and genetic evidence. -
