There is currently no cure for Huntington's disease and no way to slow or stop the brain changes it causes.

These solutions also may offer important insights into a wide range of other brain disorders, including Alzheimer's, Parkinson's disease and amyotrophic lateral sclerosis (ALS). Researchers are eager to solve these mysteries to find the answer to Huntington's. Scientists don't yet understand the normal function of huntingtin protein or how a few dozen extra repeats in its genetic blueprint lead to the devastating symptoms of Huntington's disease. Genetic tests for Huntington's disease measure the number of repeats present in an individual's huntingtin protein gene. The defect that causes Huntington's disease includes 40 or more repeats.

The normal huntingtin gene includes 17 to 20 repetitions of this code among its total of more than 3,100 codes. The huntingtin gene defect involves extra repeats of one specific chemical code in one small section of chromosome 4. The defective gene identified in 1993 causes virtually all Huntington’s disease.

The test can confirm that the defective gene for huntingtin protein is the cause of symptoms in people with suspected Huntington's disease and can detect the defective gene in people who don't yet have symptoms but are at risk because a parent has Huntington's.Įxperts strongly recommend professional genetic counseling both before and after genetic testing for Huntington's disease. A diagnostic genetic test is now available. Scientists identified the defective gene that causes Huntington's disease in 1993. Another common symptom is obsessive-compulsive behavior, leading a person to repeat the same question or activity over and over. Huntington's disease brain changes lead to alterations in mood, especially depression, anxiety, and uncharacteristic anger and irritability. Huntington's disease also causes a decline in thinking and reasoning skills, including memory, concentration, judgment, and ability to plan and organize. The hallmark symptom of Huntington's disease is uncontrolled movement of the arms, legs, head, face and upper body. Symptoms of Huntington's disease usually develop between ages 30 and 50, but they can appear as early as age 2 or as late as 80.

Defective huntingtin protein leads to brain changes that cause abnormal involuntary movements, a severe decline in thinking and reasoning skills, and irritability, depression and other mood changes.

This protein's normal function isn't yet known, but it's called 'huntingtin' because scientists identified its defective form as the cause of Huntington's disease. The defective gene codes the blueprint for a protein called huntingtin. The disorder is named for George Huntington, M.D., the physician who first described it in the late 1800s. This defect is 'dominant,' meaning that anyone who inherits it from a parent with Huntington's will eventually develop the disease. Huntington's disease is a progressive brain disorder caused by a single defective gene on chromosome 4 - one of the 23 human chromosomes that carry a person’s entire genetic code.
