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

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.91).
• BP6: Variant 2-240869070-A-C is Benign according to our data. Variant chr2-240869070-A-C is described in ClinVar as [Likely_benign]. Clinvar id is 204026.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
