SNORD3B-1 and schizophrenia: Seven genes (MARK3, RPS17, SPG7, SRA1, KANSL1, KIAA0319L, SNORD3B-1) contained placental transcripts whose individual predicted expressions were associated with schizophrenia with opposite signs (i.e., higher expression of one transcript and lower expression of the other), suggesting a link between genomic risk for schizophrenia and splicing events in the placental transcriptome (Supplementary Data 6).
