blood clotting factors
HAEMOPHILIA : It is a clinical condition in which the ability of blood clotting of a person is severly reduced, causing the sufferer to bleed severely even from a slight injury. It is also known as the bleeder's disease.
CAUSE : Haemophilia is caused due to the presence of a recessive sex-linked gene h, located on X-chromosome. There are two types of haemophilia - Haemophilia A and Haemophilia B, caused by two mutant genes present on the X-chromosome in man with a distinct gap. Haemophilia A (Royal disease) is caused due to deficiency of a protein for blood clotting known as "Factor 8" or AHF (Anti Haemophilic factor). Haemophilia B (Christmas disease) is caused due to deficiency of a protein for blood clotting known as "Factor 9" or Plasma thromboplastin.
USEFUL TO NOTE : Haemophilia is found more in males than in females.
