MalaCards based summary : Afibrinogenemia, Congenital, also known as congenital afibrinogenemia, is related to lupus erythematosus and complement factor i deficiency, and has symptoms including joint swelling, menometrorrhagia and abnormal bleeding. An important gene associated with Afibrinogenemia, Congenital is FGA (Fibrinogen Alpha Chain), and among its related pathways/superpathways are Response to elevated platelet cytosolic Ca2+ and Development Angiotensin activation of ERK. The drug Complement Factor I has been mentioned in the context of this disorder. Affiliated tissues include skin, liver and tongue, and related phenotypes are cardiovascular system and hematopoietic system

Genetics Home Reference : 25 Congenital afibrinogenemia is a bleeding disorder caused by impairment of the blood clotting process. Normally, blood clots protect the body after an injury by sealing off damaged blood vessels and preventing further blood loss. However, bleeding is uncontrolled in people with congenital afibrinogenemia. Newborns with this condition often experience prolonged bleeding from the umbilical cord stump after birth. Nosebleeds (epistaxis) and bleeding from the gums or tongue are common and can occur after minor trauma or in the absence of injury (spontaneous bleeding). Some affected individuals experience bleeding into the spaces between joints (hemarthrosis) or the muscles (hematoma). Rarely, bleeding in the brain or other internal organs occurs, which can be fatal. Women with congenital afibrinogenemia can have abnormally heavy menstrual bleeding (menorrhagia). Without proper treatment, women with this disorder may have difficulty carrying a pregnancy to term, resulting in repeated miscarriages.

UniProtKB/Swiss-Prot : 66 Congenital afibrinogenemia: Rare autosomal recessive disorder is characterized by bleeding that varies from mild to severe and by complete absence or extremely low levels of plasma and platelet fibrinogen.
