When all 10 CpG sites were analysed together in patients with schizophrenia, cg5 (B = 0.615, p = 0.007), cg6 (B = −0.695, p = 0.034), cg7 (B = 1.066, p = 0.026) and cg9 (B = −0.745, p = 0.049) were significantly correlated with mRNA expression with an overall R2 = 0.537 and overall significance of p = 0.008. This evidence concerns the gene FRRS1L and schizophrenia.
