Question

Quizplus · Accepted Answer

Hemophilia is caused by the absence or deficiency of a specific protein, factor VIII or IX, which is crucial for blood clotting. It is an inherited disorder, usually passed down through generations within families. It affects sons of carriers and can also affect daughters if they inherit the affected X chromosome from both parents. In affected individuals, bleeding may continue for an extended period or may start spontaneously without an apparent injury. There is currently no cure for hemophilia, but it can be managed with regular replacement therapy of the missing clotting factor.
