Variant summary

Our verdict is Likely pathogenic. The variant received 7 ACMG points: 7P and 0B. PM1PM2PP2PP3PP5

The NM_000030.3(AGXT):​c.125G>A​(p.Gly42Glu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000657 in 1,523,174 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G42V) has been classified as Uncertain significance.

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: Likely_pathogenic. The variant received 7 ACMG points.

PM1
In a hotspot region, there are 12 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 2 benign, 5 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, 0.832
PP5
Variant 2-240868990-G-A is Pathogenic according to our data. Variant chr2-240868990-G-A is described in ClinVar as Pathogenic. ClinVar VariationId is 204074.Status of the report is no_assertion_criteria_provided, 0 stars.
