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]

The c.1115A>G (p.Q372R) alteration is located in exon 9 (coding exon 9) of the GOT2 gene. This alteration results from a A to G substitution at nucleotide position 1115, causing the glutamine (Q) at amino acid position 372 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This variant has not been reported in the literature in individuals affected with GOT2-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.003%). This sequence change replaces glutamine, which is neutral and polar, with arginine, which is basic and polar, at codon 372 of the GOT2 protein (p.Gln372Arg). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. -
