Hemophilia: Need for Constant Blood Transfusions

What is - definition

Haemophilia is a congenital and hereditary disease. Its carriers suffer from difficult-to-control hemorrhages, which can occur either spontaneously or through minor trauma.

Understanding More About Hemophilia: Key Features

These bleedings occur due to a deficiency in the blood clotting of hemophiliacs. This genetic deficiency usually affects men most commonly.

People with this deficiency need to undergo constant blood transfusions to ensure their survival. The three most common types of hemophilia are hemophilia A, B, and C.

Haemophilia A is known as an X-linked recessive disease, ie the gene causing this deficiency is located on the X-chromosome. In the case of hemophilia A and B, these act as sex-linked recessive characters.

The daughter of a hemophilic man will have symptoms of hemophilia if he carries the defective gene on both of his two X chromosomes, which is much more difficult to do because it would require his mother to also carry a gene with this deficiency.

If your mother does not have this gene, she will only carry the gene she received from her father, and her other X chromosome (received from her mother) will be free of this deficiency. Consequently, it will not show the symptoms of hemophilia; however, your children (if they are boys) will have a 50% chance of suffering from this disease.
