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]
AGXT Gene-Disease associations (from GenCC):
  • alanine glyoxylate aminotransferase deficiency

ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 11 ACMG points.

PM1
In a hotspot region, there are 11 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 1 benign, 4 uncertain in NM_000030.3
PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 130 curated pathogenic missense variants (we use a threshold of 10). The gene has 12 curated benign missense variants. Gene score misZ: -0.26789 (below the threshold of 3.09). Trascript score misZ: -0.48778 (below the threshold of 3.09). GenCC associations: The gene is linked to alanine glyoxylate aminotransferase deficiency, primary hyperoxaluria type 1.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.996
PP5
Variant 2-240873001-G-A is Pathogenic according to our data. Variant chr2-240873001-G-A is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 204111.Status of the report is criteria_provided_single_submitter, 1 stars.
