Genes are involved in individual vulnerability to OCD
- Lewis (1936) observed that of his OCD patients, 37% had parents with OCD and 21% had siblings with OCD, suggesting that OCD runs in families
Candidate genes
- Researchers have identified genes which create vulnerability for OCD; some of these genes are involved in regulating the deveopment of the serotonin system
OCD seems to be polygenic
- OCD is not caused by one single gene, but several genes are involved
- Taylor (2013) analysed findings of previous studies and found evidence that up to 230 different genes may be involved in OCD; genes that have been studied in relation to OCD include those associated with dopamine and serotonin, which are both neurotransmitters believed to have a role in regulating mood
