A total of 26 risk SNPs within the same variant block (r2 > 0.85), covering entire ORF of KTN1 (Supplementary Fig. S1), were nominally associated with schizophrenia across at least two samples (7.5 × 10–5 ≤ p ≤ 0.049; Fig. 2); 25 of them were associated with schizophrenia across two independent European samples (7.5 × 10–5 ≤ p ≤ 0.049), which were significant after FDR correction in at least one sample (3.6 × 10–5 ≤ q ≤ 0.049). Here, KTN1 is linked to schizophrenia.
