Molecular Genetics and Human Disease Implications for Modern Psychiatric Research and Practice

Techniques of molecular genetics, including recombinant-DNA technology, are likely to have a key role in modern psychiatric research and practice. This article reviews some methods of DNA analysis and their applications to clinical science: specifically, how these methods can be used to localise, identify, isolate, and clone clinically important genes, and how this should enable us to elucidate the molecular pathology of most inherited (psychiatric) disorders. The implications of these developments for prevention and treatment of genetic disease are discussed.
