[Monogenetic causes of psychiatric disorders: a review].

BACKGROUND

Because of rapid developments in genetic technology, more underlying genetic causes of psychiatric disorders can be detected which may contribute to better monitoring and treatment of co-morbidities than previously.

AIM: Review of monogenetic causes of psychiatric disorders.

METHODE: Review of the literature.

RESULTATS: Research in people with monogenetic disorders will generate new knowledge and insights on psychopathology and cognitive function in general and pave the way to new treatment targets. In this article we discuss four monogenetic disorders that are relevant for clinical psychiatry and (educational) psychology: fragile X syndrome, tuberous sclerosis, Rett Syndrome, and Huntington’s disease.

CONCLUSION

Given the multisystem nature of these genetic disorders, a well-coordinated, multidisciplinary approach by specialized expert centers is highly recommended.
