Haemophilia (British English), or hemophilia (American English) [6] (from Ancient Greek αἷμα (haîma) 'blood' and φιλία (philía) 'love of'), [7] is a mostly inherited genetic disorder that impairs the body's ability to make blood clots, a process needed to stop bleeding.
Contaminated hemophilia blood products were a serious public health problem in the late 1970s up to 1985. [citation needed] Hemophilia A causes a deficiency in Factor VIII, a protein required for blood clotting. Factor VIII injections are a common treatment to prevent or stop bleeding in people with hemophilia A. [1]

X chromosome. The factor IX gene is located on the X chromosome (Xq27.1-q27.2). It is an X-linked recessive trait, which explains why males are affected in greater numbers. [9] [10] A change in the F9 gene, which makes blood clotting factor IX (9), causes haemophilia B. [11]
