Genes and psychosis: old wine in new bottles?
Despite initial setbacks, linkage studies with DNA markers continue to occupy center stage in psychiatric research. Advances in molecular and statistical techniques have revived the search for disease genes, leading to a new harvest of findings. Most interest in recent years has focused on potential linkages between schizophrenia and chromosomes X-Y (the pseudoautosomal region) and 22q12-13.1, and between bipolar affective disorder and chromosomes 18 (pericentromeric region) and 21q22.3. This article provides a critical evaluation of theses studies, with implications for future research. Concerns over earlier linkage trials make this scrutiny current and topical.
