An Overview of Genetics and Obsessive-compulsive Disorder

Abstract

The present status in this article, the genetics  of obsessive compulsive disorder (OCD) is discussed  (OCD). Heredity has a key role in the development of OCD.  This information is derived from a range of investigations,  involving family, double, and segregate studies conducted.  A large single gene influence as well as a genetically  determined explanation have been postulated based on  segregation research. In addition, molecular genetic  associations and connection studies have uncovered a  number of fascinating genes and genomic areas that may  play a role in OCD. As a consequence of the gene search,  classifications of the OCD phenotype have emerged, and  some of them may be considered intermediate morphologies  between it gene influence and the OCD–DSM-IV diagnosis.  Finding susceptibility genes is made more challenging by the  clinical and genetic diversity of OCD; nonetheless,  pinpointing vulnerability genes will aid in the identification  of subgroups or considerations of the condition. As a  consequence, research strategies that employ clinical  subtyping to characterize the OCD presentation in the  perspective the genetic studies might potentially aid in the  diagnosis and etiology of OCD. In OCD, the relationship  involving genetic and environmental is poorly known.  However, there have been a lot of publications that have  attempted to determine how the environment affects OCD  will be addressed.
