As the Human Genome Project completes the first human genome sequence, attention has turned to how this information can be used to understand disease. The availability of sequences for all genes will allow a comprehensive evaluation of each gene's contribution to disease. Approaches involving collecting specific gene variants and monitoring expression levels using DNA microarrays facilitate collecting information about DNA and RNA in a rapid and highly parallel manner. Developing an extensive catalogue of polymorphisms will become increasingly important in the context of studies of complex genetic diseases such as schizophrenia and bipolar disorder.
