Genetics in Psychiatry - up-to-date review 2011

Abstract

Psychiatric genetics is a popular and much-discussed topic. Many candidate genes have been investigated in relation to psychiatric disorders and many connections have been found. The utilization of these investigations is currently at a theoretical level. Nevertheless, these findings of candidate genes will be important for further research and subsequent clinical use, for example in pharmacogenetics). Due to the rapidly growing number of empirical studies that provide profound analysis of different genes and their variants in different psychiatrical symptomatology, the field is highly divided, and providing a succinct overview is challenging. This article attempts to provide an up-to-date review of the most important and most discussed genes (mainly transporter and receptor genes) contributing to the etiology of psychiatric disorders.
