Dermatoglyphics from all Chinese ethnic groups reveal geographic patterning.

ABSTRACT: Completion of a survey of dermatoglyphic variables for all ethnic groups in an ethnically diverse country like China is a huge research project, and an achievement that anthropological and dermatoglyphic scholars in the country could once only dream of. However, through the endeavors of scientists in China over the last 30 years, the dream has become reality. This paper reports the results of a comprehensive analysis of dermatoglyphics from all ethnic groups in China. Using cluster analysis and principal component analysis of dermatoglyphics, it has been found that Chinese populations can be generally divided into a southern group and a northern group. Furthermore, there has been considerable debate about the origins of many Chinese populations and about proper assignment of these peoples to larger ethnic groups. In this paper, we suggest that dermatoglyphic data can inform these debates by helping to classify a Chinese population as a northern or southern group, using selected reference populations and quantitative methods. This study is the first to assemble and investigate dermatoglyphics from all 56 Chinese ethnic groups. It is fortunate that data on population dermatoglyphics, a field of physical anthropology, have now been collected for all 56 Chinese ethnic groups, because intermarriage between individuals from different Chinese ethnic groups occurs more frequently in recent times, making population dermatoglyphic research an ever more challenging field of inquiry.

Project description:Little is known about the association of the single nucleotide polymorphism (SNP) of rs2929282 near the FERM domain containing 5 (FRMD5) and serum lipid profiles. The present study detected the association of the FRMD5 rs2929282 SNP and several environmental factors with serum lipid profiles in the Han and Jing populations. Genotyping of the FRMD5 rs2929282 SNP in 1065 subjects of Jing and 1061 participants of Han peoples was performed by polymerase chain reaction and restriction fragment length polymorphism, and then confirmed by direct sequencing. The genotypic and allelic frequencies of the SNP were different between Han and Jing (P < 0.05). The frequency of the T allele was higher in Han than in Jing (8.2% vs. 6.1%). The genotypic and allelic frequencies of the FRMD5 rs2929282 SNP were significantly different between Han males and females (P < 0.05 for each), but not between Jing males and females. The frequency of the T allele was higher in Han females than in Han males (9.3% vs. 6.5%). The FRMD5 rs2929282 T allele carriers had lower serum high-density lipoprotein cholesterol (HDL-C), apolipoprotein (Apo) A1, and ApoB levels, and higher triglyceride (TG) levels in Jing but not in Han than the T allele non-carriers. Subgroup analysis according to sex showed that the T allele carriers had higher serum TG levels in Jing females but not in males than the T allele non-carriers (P < 0.05). The T allele carriers had higher HDL-C levels in Han males but not in Han females, and lower HDL-C levels in Jing females but not in Jing males compared to the T allele non-carriers (P < 0.05). The T allele carriers had lower ApoA1 levels in Jing females but not in Jing males and lower ApoB levels in Jing males but not in Jing females than the T allele non-carriers (P < 0.05). Serum lipid traits were also associated with several environmental factors in the Han and Jing populations, and in males and females of the both ethnic groups. These findings indicated that there may be a racial/ethnic- and/or sex-specific association of the FRMD5 rs2929282 SNP and serum lipid levels.
