Congenital afibrinogenemia
（重定向自Afibrinogenemia）
Congenital afibrinogenemia is a rare, genetically inherited blood disorder in which the blood does not clot normally due to the lack of fibrinogen, a blood protein necessary for coagulation. This disorder is autosomal recessive, meaning that two unaffected parents can have a child with the disorder. The lack of fibrinogen expresses itself with excessive and, at times, uncontrollable bleeding.
