Genetic explanation of OCD

• Genetic explanation


  OCD is genetically inheritable. Certain mutated genes can increase the likelihood of developing OCD.
• SERT gene


  Responsible for serotonin reuptake in the brain. When mutated, it can lead to lower levels of serotonin at the synapse, which can contribute to low mood.
• SERT gene mutation


  Linked to patients with OCD
• COMT gene


  Involved in regulating the production of the neurotransmitter dopamine. When mutated, it can lead to higher levels of dopamine.
• COMT gene mutation


  More frequently found in patients with OCD compared to those without OCD
