The first replication cohort comprised 298 schizophrenia patients (age 37.3±11.8 yr, range 18–66) and 713 healthy controls (age 45.5±16.1 yr, range 19–72). The recruitment protocol is identical to that used for the Munich discovery sample. Schizophrenia subtypes were observed in the following proportions: paranoid 75.5%, disorganized 16.1%, catatonic 4.7% and undifferentiated 3.7%.
