title: Recent and future molecular genetic research into schizophrenia.
abstract: The difficulties anticipated in the application of molecular genetics to schizophrenia research have not prevented the first successful localization of a susceptibility gene for a subtype of schizophrenia. It is argued that this approach is the most useful of the possible molecular genetic strategies because it leads both to enhanced clinical genetic investigation and to further recombinant DNA research to clone and sequence schizophrenia susceptibility mutations. Future recombinant DNA research can now use long-range mapping and cloning techniques such as the chromosome walking/jumping approach and the strategy of cloning brain-specific cDNAs from brain mRNA. The identification of carriers for high-risk studies and the genetic validation of diagnosis appear to be the most promising clinical developments. Prenatal counseling will only become widely feasible when much more is known about the extent of heterogeneity of linkage in schizophrenia.
