what is christmas disease

Christmas disease is a genetic disorder that affects children and adults. It is caused by a mutation in the gene that produces factor VIII, a clotting protein. People with Christmas disease have a lower level of this protein, which makes it difficult for their blood to clot properly. Symptoms can vary from person to person, but common symptoms include frequent nosebleeds, easy bruising, and excessive bleeding during surgery or dental procedures. Christmas disease is treatable with infusions of factor VIII, but there is no cure.
