In the Psychiatry Genomics Consortium (PGC) ASD subset (available at: http://www.med.unc.edu/pgc/results-and-downloads), rs7180500 in GABRG3 was nominally associated with autism (OR = 0.938; SE = 0.028; p = 0.021) (Table S5), whereas rs4906902 in GABRB3 and rs4906771 in ATP10A did not show a significant association. Here, GABRB3 is linked to autism.
