Schizophrenia (MIM 181500) is a severe, common, and heterogeneous psychiatric disorder that affects 1% of the worlds population. The disorder is characterised by hallucinations, delusions, disorganised thoughts, and various cognitive and affective impairments. As a leading cause of psychiatric admissions, schizophrenia accounts for a considerable portion of healthcare expenditure and is a major public health concern.
Family, twin, and adoption studies have shown that a genetic factor is associated with susceptibility to schizophrenia.14 The number and nature of genes that influence susceptibility to schizophrenic illness, as well as their interaction with environmental factors, are unknown. Despite decades of research on anatomical, physiological, and biochemical changes possibly associated with schizophrenia, insight into the aetiology is only fragmentary. Mapping of genes that contribute to the development of schizophrenic disorders by means of linkage and association studies may help identify and characterise causal factors.
Although no single causative gene has been identified to
