Genetic Testing and Huntington's Disease

Applying Bioinfomatics Strategies in Huntingtons Disease Research

the genetic analysis of iranian patients with huntingtons disease

huntingtons disease (hd) is an autosomal dominant inherited disease characterized by involuntary movements, behavioral and personality changes, dementia and cognitive decline. although the mean age of onset is about 40 years, it varies from 5 to 79 years. therefore, at-risk individuals are never sure to have escaped the disease. hd is a member of the growing family of neurodegenerative disorder...

Huntingtin and the molecular pathogenesis of Huntingtons disease

Huntington’s disease (HD) is a late-onset neurodegenerative disorder that is caused by a CAG repeat expansion in the IT15 gene, which results in a long stretch of polyglutamine close to the amino-terminus of the HD protein huntingtin (htt). The normal function of htt, and the molecular mechanisms that contribute to the disease pathogenesis, are in the process of being elucidated. In this review...

Genetic testing for Alzheimer's disease.

Genetic factors are important in the development of Alzheimer's disease (AD). Familial AD can result from rare mutations in some genes. Other genes, such as the apolipoprotein E gene (APOE), operate as risk factors for late-onset sporadic AD. On a background of advances in the genetics of AD we suggest a way in which genetic information may be used in the diagnosis of AD. If there is a positive...

Genetic testing in cardiovascular disease.

Genetic testing is increasingly becoming possible for diagnosis, susceptibility testing, and prognostication in cardiovascular medicine. The practicing cardiologist, therefore, needs to be familiar with the clinical utilities and limitations of genetic testing. This review explores the major approaches to genetic testing and issues in test interpretation. Specific applications to cardiovascular...
