Nastadt et al. (2000) identified 80 patients with OCD and 343 of their first percentage point relatives and compared them with 73 control patients without workforcetal illness and 300 of their relatives. on that point was a strong familial link for the roughly commonalty form of this disorder. People with a first point relative with OCD (parents or siblings) had a five times great stake of having the illness themselves at some time in their lives compared with the common population.A meta-analysis of 14 mate studies of OCD, including 80 identical and 29 f judgernal twin pairs, found that identical twins were on bonny more than twice as likely to coach OCD if their twin had the disorder than were fraternal twins (Billett et al, 1998). The COMT gene:The genetic mu tation in expression of a specific gene may work to OCD. This genetic alteration reduces the production of the enzyme catechol-O-methyltransferase (COMT), which helps terminate the movement of the neurotransmitters dopamine and norepinephrine. The researchers collected DNA from samples of 73 people diagnosed with OCD and 148 who had non go through any mental disorder.

The variation in the COMT genes usual sequence, inherited from both parents, occurred in nearly half(a) of the men suffering from OCD, whereas only 1 in 10 women with OCD, and about 1 in 6 of men and women who dis depended correct mental he alth, displayed the same genetic trait. | ! integrity effectuality of the genetic explanation is that there is further empirical nourishment provided by Rasmussen & Tsuang (1986). They found a concordance rate of 53-87% in MZ twins for OCD. This suggests that there is wider academic credibility for the persuasion that genes play a significant role in the teaching of OCD.| One weakness of the genetic explanation is the nature-nurture argument.
