Molecular and clinical descriptions of patients with <scp>GABA_A</scp> receptor gene variants (<i><scp>GABRA1</scp>, <scp>GABRB2</scp>, <scp>GABRB3</scp>, <scp>GABRG2</scp></i>): A cohort study, review of literature, and genotype–phenotype correlation

GABA_A -receptor subunit variants are associated with highly variable phenotypes despite their molecular and physiological proximity. None of the genes described here was associated with a specific phenotype. On the other hand, it appears that the location of the variant on the protein may be a marker of severity. Variant location may have important weight in the development of targeted therapeutics.
