<strong>Background</strong>: Obsessive-Compulsive Disorder (OCD) is a serious neuropsychiatric disorder. The clinical prominence of the OCD symptoms dimensions and Brain-Derived Neurotrophic Factor (BDNF) Val66Met polymorphism are of significant importance. Objectives: The present study aimed to investigate the symptom dimensions and BDNF val66Met polymorphism genotype in Iranian patients with OCD.<br>
<strong>Materials and Methods</strong>: A total of 83 patients diagnosed with OCD according to the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM5) criteria, and 83 matched controls were included this case-control study. The Yale-Brown Obsessive Compulsive Scale (Y-BOCS) was used to investigate symptom dimensions. In addition, BDNF val66Met polymorphism was genotyped using Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCRRFLP) method.<br>
<strong>Results</strong>: The obtained data indicated that the most prevalent obsession was contamination (62.6%) and the most prevalent compulsion was cleanliness (69.8%). Furthermore, there was a significant relationship between the genotypes of BDNF val66Met polymorphism in OCD (P<0.01). Besides, carrying the” T” allele confers increased the risk for the presence of OCD [χ2 =4.7, P=0.003; OR (95%) 1.93 (1.24-2.99)].<br>
<strong>Conclusion</strong>: The symptoms dimensions of OCD in the Iranian sample were similar to other populations. Moreover, the findings suggested an association between BDNF val66Met polymorphism genotype and OCD in the exp
