We have completed expression microarray studies in Brodmann’s area (BA) 9 (ref. 6) and 46.7 In the study in BA 9 from subjects with schizophrenia the most differential expressed gene (increased) was SLC39A12 and, encouragingly, levels of messenger RNA (mRNA) for that gene was also significantly increased in BA 46 from subjects with the disorder. Here, SLC39A12 is linked to schizophrenia.
