ABSTRACT
<p><b>OBJECTIVE</b>To research comparatively on the RHD gene structures in unrelated RhD negative individuals of Chinese Uigur and Han population.</p><p><b>METHODS</b>The upstream, downstream, hybrid box and 10 exons of RHD gene were detected with sequence specific primer-PCR technique.</p><p><b>RESULTS</b>The results showed the genotypes of RhD negative individuals to have the significant difference between Chinese Uigur and Han population, that 94.44% Uigur individuals were with RHD(-)/RHD(-) genotype but just 61.40% Han population were with this genotype(94.44% versus 61.40%, P<0.01); 2.78% Uigur individuals were with RHD(+)/RHD(-) genotype but 34.21% Han population were with this genotype(2.78% versus 34.21%, P<0.01). However, there was significantly no RHD(+)/RHD(+) genotype difference between Chinese Uigur and Han population(2.78% versus 4.39%, P>0.05). In 78 cases of RhD negative Chinese Hans with single RHD gene, of which the RHD gene structure showed that 53(67.95%) cases were RHD(1-10) allele(of 53 RHD(1-10) alleles, 14 alleles were unexpressed); 15(19.23%) were RHD-CE(2-9)-D(2) allele; 5(6.41%) cases were RHD-CE(2-7)-D(2) allele; 2(2.56%) were similar to RHD-CE(3-6)D allele; 1(1.28%) case was RHD-CE(5-6)-D allele; and 2(2.56%) were RHD-CE(6)-D or point mutation respectively. Of 2 RhD negative Chinese Uigurs with RhD(-)/RHD(+) genotype, one carried RHD(1-10) allele, another carried RHD-CE(2-9)-D(2) allele.</p><p><b>CONCLUSION</b>The most frequently unexpressed RHD alleles were RHD-CE(2-9)-D(2), RHD(1-10) and RHD-CE(2-7)-D(2) respectively in Chinese Han population who carried single RHD allele with RHD(-) phenotype and RHD(+) genotype. It showed the confluent character of RH gene in Chinese Han and Uigur population that there existed unexpressed RHD-CE(2-9)-D(2) allele in Chinese Uigur nationality, which was infrequent in Chinese Uigur population but frequent in Chinese Han population.</p>
