Summaries for Complement Factor I Deficiency

Genetics Home Reference : 25 Complement factor I deficiency is a disorder that affects the immune system. People with this condition are prone to recurrent infections, including infections of the upper respiratory tract, ears, skin, and urinary tract. They may also contract more serious infections such as pneumonia, meningitis, and sepsis, which may be life-threatening.

MalaCards based summary : Complement Factor I Deficiency, also known as complement component 3 inactivator deficiency, is related to afibrinogenemia, congenital and hemolytic-uremic syndrome. An important gene associated with Complement Factor I Deficiency is CFI (Complement Factor I), and among its related pathways/superpathways are Innate Immune System and Toxoplasmosis. Affiliated tissues include skin, lung and breast, and related phenotypes are arthritis and renal insufficiency

Disease Ontology : 12 A complement deficiency that is characterized by recurrent pyogenic bacterial infections that is the result of complement component 3 deficiency.

OMIM : 57 Hereditary deficiency of complement factor I is associated with a propensity to pyogenic infection and follows an autosomal recessive pattern of inheritance (Vyse et al., 1996). See also complement factor H deficiency (609814), which shows overlapping clinical features. (610984)

UniProtKB/Swiss-Prot : 75 Complement factor I deficiency: Autosomal recessive condition associated with a propensity to pyogenic infections.
