摘要
在河南汉族中发现了国内首例稀有的JK(a-b-)红细胞血型。家系调查未发现第二例。先证者父母及同胞均为Jk(a+b-)型,丈夫及儿子均为Jk(a-b+)型。四个月后在广东梅县客家人中又发现一例JK(a-b-)型,先证者为一未婚女子。两位先证者血清中均无抗体。到目前为止,JK(a-b-)型在中国人群中的分布频率为2/6391(0.03％)Jk基因频率为0.0202。
The first rare Jk(a-b-) type in China was found in Han, Henan Province, but no more Jk(a-b-) in the proband's family. Her parents and sibs were Jk(a+b-) type and her husband and children were Jk(a-b+) type. The second Jk(a-b-) was found in Hakka, Mei County, Guangdong Province, four months later. This proband is a young unmarried woman. No antibody was found in both of these two proband' sera. Up to now Jk(a-b-) phenotype frequency in Chinese is 0.03%, and the gene frequency is 0.0202.
