The Crucial Role of Genetic Counseling and Testing in Huntington's Disease
Introduction
Huntington's Disease (HD) is a hereditary neurodegenerative condition characterized by motor dysfunction, cognitive decline, and psychiatric symptoms. Individuals who have a family history of HD may find themselves at risk, making genetic counseling and testing vital for assessing their potential for developing the disease. This article delves into the multifaceted role that genetic counseling and testing play for individuals at risk of Huntington's Disease.

-
Understanding Huntington’s Disease and Its Genetics
- HD is caused by a mutation in the HTT gene, leading to the production of an abnormal huntingtin protein.
- The disease follows an autosomal dominant inheritance pattern.
- Each child of an affected parent has a 50% chance of inheriting the mutated gene.
- The disease follows an autosomal dominant inheritance pattern.
- HD is caused by a mutation in the HTT gene, leading to the production of an abnormal huntingtin protein.
