Abstract

The C3, BF, C4A and C4B polymorphisms were studied in a Tunisian population sample. The allelic frequencies for C3 were S = 0.844 and F = 0.148, and for BF, S = 0.535, F = 0.331, SO7 = 0.075 and F1 = 0.041. The most frequent C4 alleles were A3 and B1 followed in a decreasing order by A2, B2 and the A and B null alleles. The results indicate that the Tunisian population is intermediate between the Caucasian and Arab populations with some trace admixture of African Blacks.

摘要

在突尼斯人群样本中研究了C3、BF、C4A和C4B的多态性。C3的等位基因频率为S = 0.844，F = 0.148；BF的等位基因频率为S = 0.535，F = 0.331，SO7 = 0.075，F1 = 0.041。最常见的C4等位基因是A3和B1，其次按降序排列为A2、B2以及A和B无效等位基因。结果表明，突尼斯人群介于高加索人群和阿拉伯人群之间，有一些非洲黑人的微量混合血统。
