GABRA5 and autism: RT-qPCR analysis revealed reduced mRNA expression levels of subunit genes gabra1, gabra2a, gabra4, gabra5, gabra6b, gabrb2a, gabrg1, and gabrd, and multiple GABAA receptor subunits, including GABRG1, GABRA2, GABRA4, and GABRA5 have been linked to autism by genetic analyses [57,58,59].
