Study reveals information about risk genes in schizophrenia Dr. Felix-Martin Werner, working at the Euro Academy Pößneck in Germany and Prof. Rafael Coveñas, working at the Institute of Neurosciences of Castilla and León, Salamanca in Spain, have been working on neurological and psychiatric disease for over ten years. In their most recent review, published in Current Pharmaceutical Design (Bentham Science Publishers) Werner and Coveñas cover information about the risk genes in schizophrenia and explain the importance of examining their single nucleotide polymorphisms (SNP's). In schizophrenia, 260 risk genes have been discovered, and an association between single SNPs and the clinical efficacy of a specific antipsychotic drug has been established.
