Interestingly, within the network, we also observed several genes previously reported to be associated with schizophrenia, including ABCB1, ANK3, ATXN1, BDNF, CHRNA7, GABRA1, GABRG2, NPY, and PRKACA[31], indicating their potential co-morbidity. This evidence concerns the gene CHRNA7 and schizophrenia.
