More recently, schizophrenia-association was established for GABRB2 located at chromosome 5q34, and its genotypes have been correlated to splicing variations of β2-subunit isoforms that give rise to different electrophysiological consequences in type A γ-amino-butyric acid (GABAA) receptor function [5], [6], [7]. Here, GABRB2 is linked to schizophrenia.
