Which of the following are true about a haemophilic patient?
Genes that control protein synthesis become defective.
A large amount of blood is lost even through minor wounds.
It is an example of a genetic disease.
The clotting of blood in wounds prevents excessive loss of blood in healthy individuals. Blood clots with the help of proteins present in blood plasma. The synthesis of these proteins fails when the genes that control its synthesis become defective. Hence, clotting fails and there is excess blood loss even through minor wounds. This condition is called haemophilia. Haemophilia is a genetic disease and so a complete cure is not available at present. Temporary relief is brought in by injecting the deficient proteins identified through clinical diagnosis.
