title: Distribution of complement C3 variants in individuals with cystic fibrosis.
abstract: The gene frequency for slow and fast electrophoretic variants of complement C3 in Caucasian individuals with cystic fibrosis was similar to the values expected for unaffected controls, thereby ruling out a suspected differential involvement of these phenotypes with the disease. In one family, cystic fibrosis and complement C3 phenotypes segregated independently.
