The placental TWAS associations show a pattern of relatively limited concordance between schizophrenia and autism (r = 0.1079, Fig. 4a), and the two placental genes associated with autism were also associated with schizophrenia with nominal levels of significance (RPS15AP1: p = 0.001, FDR = 0.028; RP1-198K11.5: p = 0.046, FDR = 0.061, Supplementary Data 44–54). The gene discussed is RPS15AP1; the disease is autism.
