Brief Background

This is a rare disorder that is characterised by premature aging [1]. The syndrome was discovered by Jonathan Hutchinson and Hastings Gilford [2] and it occurs in 1 in 8 million people.

Cause

It is due to a completely random point mutation at the 1824th position of the Lamin A protein leading to the substitution of thymine with cytosine [3]. It is said to be completely random as there is no specific tribe or race associated with it. It has been discovered in patients across the globe.  Although their is no current evidence that the syndrome can be inherited their is a family in India that all the children have the syndrome.

Symptoms

  1. Alopecia
  2. Delayed tooth formation
  3. Scleroderma
  4. Macrocephaly
  5. Prominent scalp veins
  6. Bulging eyes
  7. High pitched voice
  8. Growth failure
  9. Loss of muscles and body fat
  10. Progressive cardiovascular diseases
  11. Progressive atherosclerosis
  12. Death [4] 

Treament

Drugs - pravastatin and zoledronate

Pravastin helps to prevent cardiovascular related diseases while zoledronate helps to prevent skeletal fractures in patients.[5]
