There was a positive significant correlation between the mRNA level of NDUFV1 and age at onset of the disease (r = 0.21; P = 0.04), and a positive correlation between the mRNA level of NDUFV2, and BPRS score (r = 0.31, P = 0.03) and SAPS score (r = 0.2, P = 0.04) in the first-episode schizophrenia patients. This evidence concerns the gene NDUFV1 and schizophrenia.
