In addition, it was shown that polymorphism in the bromodomain motif of the switch/sucrose non‐fermentable (SWI/SNF) related, matrix associated, actin dependent regulator of chromatin, subfamily A, member 2 (SMARCA2), which encodes Brahma in the SWI/SNF chromatin‐remodelling complex, is associated with the development of schizophrenia 7. This evidence concerns the gene SMARCA1 and schizophrenia.
