Complement C6 deficiency

Complement component C6 deficiency is an autosomal recessive disorder caused by mutations in the C6 gene which may results in various immonological condition such as impaired defense of infections and autoimmune phenomena, but often the deficiency is asymptomatic.


C6 deficiency has a frequency of about 1/40000 in Japan.[Error: Macro 'ref' doesn't exist]
