Do you know about Huntington’s disease? A genetic disorder

Huntington’s disease is a genetic disorder which can be fatal in nature. It is caused by a defect in a single gene which causes mutant proteins. It also causes progressive breakdown of nerve cells in the brain and deteriorates a person’s physical and mental abilities.

It is known as quintessential family disease because every parent who has Huntington disease has 50% chances that his child will be affected with that disease by carrying the defective gene.

It affects the whole brain.


Symptoms usually appear in the age between 30 to 50.

• Pneumonia, heart failure
