What is the primary genetic mutation responsible for Huntington's disease?
What is the primary genetic mutation responsible for Huntington's disease?
The primary genetic mutation responsible for Huntington's disease is the overproduction of the genetic sequence CAG, leading to excessive Huntington protein.

Study Notes
Huntington's Disease
- Incurable hereditary brain disorder
- Causes degeneration of brain cells
- Affects motor functions, thinking ability, and behaviors
- Affects approximately 1 in 10,000 people
- Symptoms typically appear between ages 30 and 40, but can remain dormant until then
- Affects males and females equally
- Caused by a cellular mutation (Huntington) resulting in excessive production of a specific gene sequence (CAG)
- A 50/50 chance of inheriting the HD gene as each person receives one chromosome from each parent.
Physical Effects
- Movement: Jerking, uncontrolled movements, slow eye movement, speech/swallowing difficulties
- Cognitive: Difficulty with information processing, organization, disorientation, repetitive thoughts/focusing issues
Psychiatric Effects
- Possible symptoms: Depression, aggression, anxiety, sadness, often resulting in physical and cognitive impairment
- Increased risk: Suicide and alcoholism
Diagnosis and Treatment
- Diagnosis involves physical and psychological evaluations to determine symptom onset
- Treatment involves rating scales based on motor, cognitive, and behavioral symptoms
- Huntington's disease is currently incurable
- Medications may be used to lessen symptoms.
