Popis: Publisher Summary This chapter focuses on finding liability genes for schizophrenia. Concordance rates for schizophrenia are consistently higher in monozygotic (MZ) than in dizygotic (DZ) twins, with proband-wise MZ concordance rates averaging 46% versus DZ rates of about 14%. Research into the molecular genetics of schizophrenia is entering a new phase of optimism. Currently, the main challenge for the field is how to convert tentative and suggestive findings of linkage into confident assignments to well-circumscribed regions of the genome. This is almost involving the analysis of large samples of affected sibling-pairs and of large unrelated patient samples for linkage disequilibrium. A second challenge is the optimization of techniques that allows large samples to be analyzed in a realistic time frame. Finally, methods are also required that allows the high-throughput mutational analysis of many genes within candidate regions.
