Genes with literature support to be associated with schizophrenia that could only be identified using splicing data in the MHC region includes NOTCH4 (MSG p-value = 8.35 × 10−29; S-PrediXcan p-value = 8.19 × 10−2) [58], TRIM26 (MSG p-value = 4.64 × 10−14; S-PrediXcan p-value = 4.40 × 10−1) [59], and ZSCAN9 (MSG p-value = 4.64 × 10−14; S-PrediXcan p-value = 4.40 × 10−1) [60]. This evidence concerns the gene ZSCAN9 and schizophrenia.
