NDEL1 and mental disorder: NDEL1 downregulation was reported in the hippocampus and blood of patients with schizophrenia.18 Notably, NDEL1 is a known DISC1 interactor, which has been associated with schizophrenia and other major mental disorders.19 Here, we found that two SNPs regulated DISC1 expression, corroborating their role as eQTLs for whole blood found in GTEx, and even more interesting, these SNPs were associated with SZ in an indirect way, via DISC1 expression.
