GABRB2 and schizophrenia: The first identification of a GABAergic pathway gene as a robust schizophrenia candidate gene was obtained by us based on the association of intronic single nucleotide polymorphisms (SNPs) in a 3551-bp segment in the vicinity of the AluYi6AH-151 insertion in the GABAA receptor β2 subunit gene (GABRB2) with schizophrenia in Chinese7, and later confirmed in other populations8,9.
