Abstract: | The polymorphism of C7 was investigated in neuraminidase-treated sera from 513 unrelated Japanese individuals using isoelectric focusing followed by an electroimmunoblotting technique. Besides the common phenotypes 5 rare variants including 2 types of new variants were detected. The family analysis suggested the hereditary occurrence of a new allele C7*8. The allele frequencies were: C7*1 = 0.8314, C7*2 = 0.0926, C7*3 = 0.0380, C7*4 = 0.0331, C7*6 = 0.0010, and C7*8 = 0.0039. |
