Is Afibrinogenemia hereditary?

Afibrinogenemia is a rare inherited bleeding disorder characterized by the absence or severe deficiency of fibrinogen, a protein essential for blood clotting. This condition is caused by mutations in one or more of the three genes responsible for producing fibrinogen: FGA, FGB, and FGG.

Afibrinogenemia follows an autosomal recessive pattern of inheritance. This means that an individual must inherit two copies of the mutated gene, one from each parent, to develop the disorder. If both parents carry a single copy of the mutated gene, they are considered carriers and have a 25% chance of having an affected child with each pregnancy.

Since afibrinogenemia is a hereditary condition, it can be passed down through generations within families. However, it is important to note that not all individuals with a family history of afibrinogenemia will necessarily develop the disorder. Some individuals may inherit only one copy of the mutated gene and become carriers without experiencing any symptoms.

Diagnosis of afibrinogenemia is typically confirmed through laboratory tests that measure fibrinogen levels in the blood. Symptoms of the disorder can vary widely, ranging from mild to severe, and may include excessive bleeding, easy bruising, nosebleeds, and prolonged bleeding after injury or surgery.

Treatment for afibrinogenemia involves replacing the missing or deficient fibrinogen. This can be done through infusions of cryoprecipitate, fresh frozen plasma, or purified fibrinogen concentrates. Additionally, individuals with afibrinogenemia should work closely with a healthcare team specializing in bleeding disorders to manage and prevent bleeding episodes.
