cause of haemophilia

Haemophilia is indeed a genetic disorder caused by mutations in specific genes responsible for producing the clotting factors essential for blood coagulation. It’s classified into haemophilia A or B, depending on whether the deficiency is in clotting factor VIII or IX respectively. These genes are located on the X chromosome, so haemophilia is typically an X-linked recessive condition—meaning it’s more common in males who have just one X chromosome. Females have two X chromosomes and are usually carriers; they’d need mutations in both copies of the gene to exhibit the disorder, which is rare. However, female carriers may have mild symptoms.

The genes can be passed from a carrier mother or less commonly, can result from a new mutation in the child. If the father’s got haemophilia, his daughters will be carriers but sons won’t be affected. With regards to your son leading a “normal” life, with modern treatment, most individuals with haemophilia can live healthy lives. Prophylactic infusions of the deficient clotting factor, either regularly or as needed, help manage bleeding risks.

While you want to protect and ease your son’s life, education is key. As he grows, teaching him about managing his condition, recognizing when he needs medical attention, and avoiding high-risk activities is crucial. Pediatric haematologists can provide disease-specific information and make referrals to haemophilia treatment centers for regular check-ups. Psychological support for him and your family can be beneficial too, ensuring everyone’s prepared emotionally.
