PATHOLOGY

Detailed explanation-1: -Hemophilia A and hemophilia B are inherited in an X-linked recessive pattern . The genes associated with these conditions are located on the X chromosome, which is one of the two sex chromosomes . In males (who have only one X chromosome), one altered copy of the gene in each cell is sufficient to cause the condition.

Detailed explanation-2: -Hemophilia is caused by a mutation or change, in one of the genes, that provides instructions for making the clotting factor proteins needed to form a blood clot. This change or mutation can prevent the clotting protein from working properly or to be missing altogether. These genes are located on the X chromosome.

Detailed explanation-3: -Hemophilia is a bleeding disorder in which blood does not clot properly. Blood contains many proteins, called clotting factors, that can help to stop bleeding after injury or surgery.

Detailed explanation-4: -Overview. Hemophilia is a rare disorder in which the blood doesn’t clot in the typical way because it doesn’t have enough blood-clotting proteins (clotting factors). If you have hemophilia, you might bleed for a longer time after an injury than you would if your blood clotted properly.

Detailed explanation-5: -Hemophilia involves an inherited deficiency of certain clotting factors (proteins that help the blood clot, stopping bleeding). In hemophilia A, clotting factor VIII is deficient and in hemophilia B, factor IX is deficient. However, rarely people have an inherited deficiency of another clotting factor.
