Genes affected

GOT2 (HGNC:4433): (glutamic-oxaloacetic transaminase 2) Glutamic-oxaloacetic transaminase is a pyridoxal phosphate-dependent enzyme which exists in cytoplasmic and inner-membrane mitochondrial forms, GOT1 and GOT2, respectively. GOT plays a role in amino acid metabolism and the urea and tricarboxylic acid cycles. The two enzymes are homodimeric and show close homology. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2013]

ACMG classification

Verdict is Likely_benign. Variant got -4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.86).
• BP6: Variant 16-58708310-A-C is Benign according to our data. Variant chr16-58708310-A-C is described in ClinVar as [Likely_benign]. Clinvar id is 2743771.Status of the report is criteria_provided_single_submitter, 1 stars.
