Prothrombin mutation refers to a genetic alteration in the gene that encodes prothrombin, a protein involved in the blood clotting process. Prothrombin is a vitamin K-dependent protein that is synthesized in the liver and plays a crucial role in the coagulation cascade, converting into thrombin, which then converts fibrinogen into fibrin, forming a blood clot.

Mutations in the prothrombin gene can lead to various inherited coagulation disorders, collectively known as prothrombin deficiencies. These deficiencies can be classified into two main types: quantitative and qualitative. Quantitative deficiencies result from reduced levels of prothrombin, while qualitative deficiencies involve functional abnormalities in the prothrombin protein.

Prothrombin mutation can cause bleeding disorders, characterized by prolonged bleeding time and increased risk of hemorrhage. The severity of symptoms varies depending on the type and extent of the mutation. In some cases, the condition may be asymptomatic, while in others, it can lead to significant health issues, including spontaneous bleeding, excessive menstrual bleeding, and life-threatening bleeding episodes.

Diagnosis of prothrombin mutation typically involves blood tests to measure prothrombin levels and assess its function. Treatment options may include vitamin K supplementation, blood transfusions, and, in severe cases, factor concentrates or recombinant factor VIIa. Genetic counseling and family screening are also recommended to manage the condition and reduce the risk of transmission to offspring.
