Genetic Test
The F9 gene encodes a protein that is a vitamin K-dependent coagulation factor IX, essential for hemostasis, and circulates in the blood to activate coagulation. Variants in this gene cause hemophilia B.
Disease Description
Factor IX deficiency is a genetic disorder caused by impaired blood coagulation activity. Also known as hemophilia, it can result in prolonged bleeding at sites of injury, the umbilical cord after birth, nose, mouth, eyes, and other locations.
