Abstract

We analysed six multiplex pedigrees of schizophrenia for linkage to two DNA probes mapping to the chromosome 5q11–q13 region where linkage to a gene for schizophrenia was recently reported. Analyses were conducted using three penetrance models and considering the affected state to be schizophrenia, the schizophrenia spectrum, and all psychiatric diagnoses. All analyses gave consistently negative lod scores. Although the region was not formally excluded, no evidence for linkage was found.
