CTNNA1 and schizophrenia: Four genes in females (MAD1L1, Metazoa_SRP, CNNM2, RPS17) and eight genes in males (BAP1, ACY1, KANSL1, CHMP1A, CTNNA1, EIF5, CLP1, SNORD3B-1) contained placental transcripts whose individual predicted expression was associated with schizophrenia with opposite directionality, suggesting that the link between genomic risk for schizophrenia and splicing events in the placental transcriptome is not biased by sex-related differences (Supplementary Data 16,19).
