Huntington’s Disease

  • Context (TH): A paper published by researchers from the University of Szeged has made strides in understanding Huntington’s Disease using fruit flies.
  • It is a rare, progressive genetic disorder that causes progressive breakdown of brain’s nerve cells.
  • It is caused by a mutation in the HTT gene which is involved in the production of a protein called huntingtin which provides instructions for making the protein.
  • Mutated genes provide faulty instructions leading to the production of abnormal huntingtin proteins and the formation of clumps.
  • These clumps disrupt the normal functioning of the brain cells, which eventually leads to the death of neurons in the brain, resulting in Huntington’s disease.
  • The symptoms often appear when a person is in their 30s or 40s.
  • It causes uncontrolled movements, impaired coordination of balance and movement, a decline in cognitive abilities, difficulty in concentrating and memory lapses, mood swings, and personality changes.
  • Treatment: No cure exists, but drugs and physiotherapy can help manage some symptoms.
