Association study between the -62A/T NFKBIL1 polymorphism and obsessive-compulsive disorder
New Jersey Center for Tourette Syndrome Sharing Repository: methods and sample description
<p>Abstract</p> <p>Background</p> <p>Tourette Syndrome is a neuropsychiatric disorder characterized by chronic motor and phonic tics. Affected individuals and their family members are at an increased risk for other neuropsychiatric conditions including obsessive-compulsive disorder and attention deficit hyperactivity disorder. While there is consistent evidence that genetic factors play a significant etiologic role, no replicable susceptibility alleles have thus far been identified.</p> <p>Description</p> <p>Here we discuss a sharing resource of clinical and genetic data, the New Jersey Center for Tourette Syndrome Sharing Repository, whose goal is to provide clinical data, DNA, and lymphoblastoid cell lines to qualified researchers.</p> <p>Conclusion</p> <p>Opening access to the data and patient material to the widest possible research community will hasten the identification of causal genetic factors and facilitate better understanding and treatment of this often impairing disorder.</p
Association analysis between a VNTR intron 8 polymorphism of the dopamine transporter gene (SLC6A3) and obsessive- compulsive disorder in a Brazilian sample
Distonia primária e transtorno obsessivo-compulsivo Primary dystonia and obsessive-compulsive disorder
OBJETIVO: Uma maior freqüência de transtorno obsessivo-compulsivo (TOC) em pacientes com distonia primária vem sendo relatada na literatura. O objetivo deste trabalho é revisar os estudos que investigaram a associação entre TOC e distonia primária. MÉTODOS: Artigos que correlacionaram ambas as condições, incluindo estudos caso-controle, descritivos, relatos e série de casos, foram selecionados. As bases de dados avaliadas foram Medline e Lilacs. RESULTADOS: Foram encontrados 12 artigos, sendo 8 estudos caso-controle e 4 séries ou relatos de casos. Metade dos estudos caso-controle observou mais sintomas obsessivo-compulsivos nos pacientes com distonia em relação a controles, enquanto a outra metade não. CONCLUSÃO: Os resultados são conflitantes, não sendo possível estabelecer uma conclusão definitiva acerca da associação entre distonia e TOC.<br>OBJECTIVE: Patients with primary dystonia have been reported to have a major incidence of obsessive-compulsive disorder (OCD). The objective of the present work is to review the studies that investigated the association between OCD and primary dystonia. METHODS: Articles that correlated both conditions, including case-control and descriptive studies as well as case-reports and series, were selected. Articles were searched on Medline and Lilacs. RESULTS: Twelve articles were found, and eight were case-control studies. In half of case-control studies, obsessive-compulsive symptoms were more common in patients with dystonia than controls, while in the other half there was no such a difference. CONCLUSION: As the results are controversial, definite conclusion regarding the association between dystonia and OCD cannot be established

COMT and MAO-A polymorphisms and obsessive-compulsive disorder: a family-based association study.
Obsessive-compulsive disorder (OCD) is a common and debilitating psychiatric illness. Although a genetic component contributes to its etiology, no single gene or mechanism has been identified to the OCD susceptibility. The catechol-O-methyltransferase (CO
