Obsessive-compulsive disorder (OCD) is a psychiatric condition that affects both children and adults. In the last years, it has been shown that genetic and environmental factors contribute to the etiology of this disease. By applying genetic mapping techniques, different genes were observed to be associated with OCD. Moreover, it has also been discovered that OCD is a trait that has a complex pattern of inheritance (i.e., it is a quantitative trait).
