Genetic polymorphism of the C1R subcomponent of human complement component C1 has been detected in normal plasma samples using the high resolving power of isoelectric focusing in 6 M urea followed by immunoblotting. There are two common alleles at the C1R structural locus that show autosomal codominant inheritance. The C1R*1 and C1R*2 allele frequencies in U.S. white and U.S. black blood donors are: .934, .066, and .899, .101, respectively.
