Neuroanatomical Intermediate Phenotypes in Chinese Patients with Schizophrenia K SIM1, WY CHAN2, HQ LOW3, GL YANG4, PS WOON2, YY SITOH5, JJ LIU3, WL NOWINSKI4 1General Psychiatry, Institute of Mental

Neuroscience Institute, Singapore Background/Hypothesis: There are notable similarities between Velo-Cardio-Facial Syndrome (VCFS) and schizophrenia in terms of neurocognitive deficits and brain structural abnormalities. These similarities have supported the role of the armadillo repeat gene deleted in VCFS (ARVCF gene) as a susceptibility gene in schizophrenia. This study investigates the relationships between haplotypes of ARVCF gene and specific intermediate phenotypes in schizophrenia. Based on extant data, we hypothesise that specific ARVCF gene haplotypes reduce the caudate nucleus volume, fractional anisotropy and neurocognitive functioning in schizophrenia. Methods: Blood samples from 200 Chinese participants (125 schizophrenia patients and 75 healthy controls) were genotyped, a subset of 166 participants underwent structural magnetic resonance imaging
