Final answer:
Hemophilia is a genetic disorder caused by a deficiency of clotting factors, leading to excessive bleeding and other complications. It predominantly affects males and can require regular factor infusions, with genetic therapy being a prospective treatment.
Step-by-step explanation:
The result of the effects of a single gene loss resulting in symptoms such as excessive bleeding, bruising, joint pain and swelling, vision loss, anemia, or neurological problems, is a genetic disorder known as hemophilia. Hemophilia is characterized by a deficiency in the blood's clotting factors, primarily factor VIII for hemophilia A and factor IX for hemophilia B. These clotting factors are essential for blood coagulation, and their absence can lead to severe bleeding issues. Hemophilia A and B are linked to the X chromosome, affecting males predominantly, but hemophilia C, related to factor XI, can affect both sexes. People with hemophilia may require regular infusions of clotting factors and, in the future, could benefit from genetic therapy.
