Applied neurogenomics

Neurogenomics, the study of the genes of the nervous system, has applications in basic research, in the pharmaceutical industry and in the management of neurological disorders. Basic research applications include molecular neuropathology, the detection of genes for neurological disorders, the study of gene expression in the CNS and creation of transgenic models of neurological disorders. Pharmaceutical applications may be in the areas of molecular neuropharmacology, the discovery of new drugs for neurological disorders, gene therapy and the development of personalised medicines based on pharmacogenomics. Clinical applications in neurology include the redefinition and reclassification of diseases, molecular diagnostics and the integration of diagnostics with therapeutics. Various methods for the study of genes and gene expression are described. Genes have been identified for only a limited number of neurological disorders so far. The discovery of genes defective in neurological disorders would facilitate drug discovery, molecular diagnostics and gene therapy diseases. There is a trend towards the integration of diagnosis, genetic screening, prevention, treatment and monitoring of therapy of neurological disorders, which will be facilitated by neurogenomics. Pharmacogenomics-based personalised medicines are anticipated to be part of medical practice by the end of the first decade of the 21st century, and neurogenomics will contribute to the development of personalised medicines for diseases of the CNS.
