We investigated the association between the long (l) and short (s) alleles of the serotonin transporter polymorphism (5‐HTTLPR) in the promoter region of the SLC6A4 gene and obsessive‐compulsive disorder (OCD) using meta‐analysis to combine all published data from case–control and family based association studies (2,283 cases). In stratified meta‐analysis we investigated whether age of sample (child and adult), ethnicity (Caucasian and Asian) and study design (case–control and family‐based…

TLDR
It is demonstrated that OCD is associated with multiple genes, with most having a modest association with OCD, which suggests a polygenic model of OCD, consistent with twin studies, in which multiple genes make small, incremental contributions to the risk of developing the disorder.
Combining genetic and epigenetic parameters of the serotonin transporter gene in obsessive-compulsive disorder.
Association of serotonin transporter gene polymorphisms with obsessive-compulsive disorder (OCD) in a south Indian population
TLDR
Genetic variation in the SLC6A4 gene regulatory region may not have a significant effect on OCD in the present population of OCD patients and controls of south Indian origin.
Lack of Evidence For Association Between Serotonin Transporter Gene Polymorphism and Obsessive Compulsive Disorder fienel
TLDR
The authors could not find any evidence for the association of 5-HTTLPR and 5- HTT VNTR polymorphisms with OCD, response to treatment with serotonin reuptake inhibitors, positive family history for OCD and presence of tics.
Is serotonin transporter polymorphism (5-HTTLPR) allele status a predictor for obsessive-compulsive disorder? A meta-analysis
TLDR
The findings provide further support for the need of subtype classification of this heterogeneous disorder and emphasis should be placed on the effect of female reproductive milestones on OCD onset and symptom exacerbation.
Association of the functional serotonin transporter haplotype with familial form of obsessive compulsive disorder in Iranian patients
TLDR
The association of SLC6A4 variants with familial form of OCD was showed and proposed stratified analyses in the genetic studies facilitate identification of genetic risk factors for this heterogeneous disorder.
Association of SLC6A4 variants with obsessive-compulsive disorder in a large multi-center US family study
TLDR
Evidence is found of genetic association at the SLC6A4 locus with OCD using the Family-Based Association Test (FBAT) under additive, dominant, recessive and genotypic models, using both OCD and sex-stratified OCD as phenotypes.
Serotonin transporter promoter polymorphism is associated with executive function impairments in patients with obsessive compulsive disorder
TLDR
The findings suggest that the high-expressing variant of 5-HTTLPR polymorphism may be associated with lower performance on some abstraction and planning measures in OCD patients.
Sex determines which section of the SLC6A4 gene is linked to obsessive-compulsive symptoms in normal Chinese college students.

TLDR
Haplotype-based haplotype relative risk and transmission disequilibrium analysis did not show a preferential transmission of l allele to OCD probands, indicating the need to analyse larger samples using family-based methods.

TLDR
There is a strong association between the serotonin transporter promoter variant and neuroticism as measured in the NEO personality inventory and that non‐replications are largely due to small sample size and the use of different inventories.

TLDR
Evidence that variation in SLC6A4 plays a significant role in the development of OCD in the population groups studied is inconclusive, and future association studies in Caucasian populations may extend the power of such meta-analyses and assist in delineating the role of SLC 6A4 in OCD.

TLDR
Allelic variation at 5‐HTTLPR contributes to risk for AD, with the greatest effect observed among individuals with a co‐occurring clinical feature.

Although modulation of symptoms of obsessive-compulsive disorder (OCD) by serotonergic agents is well established, it is unclear whether an abnormality in the central serotonergic system is involved

TLDR
The SERTPR polymorphisms affect certain factors of OC symptoms, and the factor analytic approach used in the present study has identified meaningful symptom dimensions to help guide future research.
