White matter volume and myelin oligodendrocyte glycoprotein (MOG) microsatellites in pediatric obsessive-compulsive disorder.
The myelin oligodendrocyte glycoprotein ( MOG ) gene plays an important role in myelination and has been implicated in the genetics of white matter changes in obsessive-compulsive disorder (OCD). We examined the association between variations of two microsatellite markers across MOG for association and total white matter volume as measured using volumetric MRI in 37 pediatric OCD patients 7-18 years. We compared white matter volumes between microsatellite allele groups using analysis of covariance with covariates of age, gender, and total intracranial volume. After controlling for multiple comparisons, a significant relationship was detected between MOG (TAAA)n and increased total white matter volume ( P = 0.018-0.028). Although preliminary, our findings provide further support for the involvement of MOG in OCD.
期刊介绍：
The journal aims to publish papers which bring together clinical observations, psychological and behavioural abnormalities and genetic data. All papers are fully refereed.
Psychiatric Genetics is also a forum for reporting new approaches to genetic research in psychiatry and neurology utilizing novel techniques or methodologies. Psychiatric Genetics publishes original Research Reports dealing with inherited factors involved in psychiatric and neurological disorders. This encompasses gene localization and chromosome markers, changes in neuronal gene expression related to psychiatric disease, linkage genetics analyses, family, twin and adoption studies, and genetically based animal models of neuropsychiatric disease. The journal covers areas such as molecular neurobiology and molecular genetics relevant to mental illness.
Reviews of the literature and Commentaries in areas of current interest will be considered for publication. Reviews and Commentaries in areas outside psychiatric genetics, but of interest and importance to Psychiatric Genetics, will also be considered.
Psychiatric Genetics also publishes Book Reviews, Brief Reports and Conference Reports.
