Variant summary

Our verdict is Benign. The variant received -17 ACMG points: 3P and 20B. PM1PP2BP4_StrongBP6_Very_StrongBA1

The NM_000030.3(AGXT):c.590G>A(p.Arg197Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00453 in 1,613,450 control chromosomes in the GnomAD database, including 207 homozygotes. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R197W) 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]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -17 ACMG points.

PM1

In a hotspot region, there are 17 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 5 uncertain in NM_000030.3

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.

BP4

Computational evidence support a benign effect (MetaRNN=0.003585279).

BP6

Variant 2-240873044-G-A is Benign according to our data. Variant chr2-240873044-G-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 92312.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BA1

GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.0662 is higher than 0.05.

Review Status:criteria provided, single submitter

Collection Method:clinical testing

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). No publications were found based on this search. Allele frequency data from public databases allowed determination this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -
