The frequencies of human leukocyte antigen (HLA) alleles HLA-A, -B, and -DRB1 alleles and A-B-DRB1, A-B, and B-DRB1 haplotypes were studied in Jinuo and Wa populations in Southwest China using the polymerase chain reaction-Luminex (PCR-Luminex) typing method. A total of 12 A, 22 B, and 16 DRB1 alleles were found in the Jinuo population, and 10 A, 28 B, and(More)
Population migrations in Southwest and South China have played an important role in the formation of East Asian populations and led to a high degree of cultural diversity among ethnic minorities living in these areas. To explore the genetic relationships of these ethnic minorities, we systematically surveyed the variation of 10 autosomal STR markers of(More)
Killer cell immunoglobulin-like receptors (KIRs) show extensive variation in terms of gene content and allelic polymorphisms among different populations. The aim of this study was to analyze the distribution of KIR genes in the Bulang, Nu, Yugu, and Zhuang ethnic groups, which belong to four different language families in China, and thus to provide basic(More)
Tai people are widely distributed in Thailand, Laos and southwestern China and are a large population of Southeast Asia. Although most anthropologists and historians agree that modern Tai people are from southwestern China and northern Thailand, the place from which they historically migrated remains controversial. Three popular hypotheses have been(More)
Polymorphisms of CCR5, CCR2, SDF, and CX3CR1 were reported to be involved in HIV-1 infection or the development of disease progression to AIDS. Cohort studies showed that CCR5-Delta32, SDF1-3'A, and CCR2-64I were protective, which could provide resistance to HIV-1 infection or delay disease progression, although the effect of SDF1-3'A homozygosity in the(More)
We performed a mitochondrial whole-genome comparison study in 40 Tibetan and 50 Han Chinese. All subjects could be classified into 13 haplogroups pertained to the Macrohaplogroup M and N that pitched different quadrants by principal component analysis. We observed a difference in the M9 haplogroup and identified 18 significant variants by comparing whole(More)
As the world's most populous nation, China exhibits a population with 56 nationalities. We already know the associations between genetic relationship of these ethnic groups in China and their geographic distributions are closely. However, the correlations between genetic diversity and linguistic affinities have still not been fully revealed in China. To(More)
OBJECTIVE The aim of this study was to determine the distribution and origin of hemoglobin E (HbE) in seven minority groups from various geographical regions of the malaria-endemic Yunnan province, southwestern China, which have similar ethnic origins and geographic relationships with HbE-prevalent populations of Southeast Asian countries. METHODS By(More)
The genetic diversity and relationships among ethnic minority populations of southwest China were investigated using seven polymorphic restriction enzyme sites in the β-globin gene cluster. The haplotypes of 1392 chromosomes from ten ethnic populations living in southwest China were determined. Linkage equilibrium and recombination hotspot were found(More)
Echovirus 6 (E6) infections are associated with aseptic meningitis and acute flaccid paralysis (AFP). But some infections, sometimes most of them, are asymptomatic. The mechanism of E6 virulence is unknown. Analyses of the molecular evolution of asymptomatic E6 may help understand why the infections show different manifestations. Ninety-six stool samples of(More)
