25771305 This study utilized ER+ IBC to identify a metagene including ABAT and STC2 as predictive biomarkers for endocrine therapy resistance.
25485164 A-to-G transition at nucleotide 754 of the human ABAT gene identified in lymphoblast cDNA (c.754A>G) results in substitution of an invariant arginine at amino acid 220 by lysine (p.Arg220Lys). This point mutation results in destabilization of the binding of pyridoxal-5'-phosphate to GABA-transaminase (required for transamination of GABA to succinic semialdehyde) and thus results in GABA-transaminase deficiency.
22225676 Findings point to a possible role of ABAT gene-regulated GABA catabolism for an altered processing of somatosensory stimuli as a potential vulnerability marker for affective disorders.

15528998 results suggest that the Cys321 residue is essential for the catalytic function of GABAT, and that it is involved in the formation of a disulfide link between two monomers of human brain GABAT
12694932 Marked differences in platelet uptake of GABA and activity of catabolic enzyme GABA-T between patients with generalized and localization-related epileptic syndromes. May indicate an impairment in function of brain GABAergic systems.
