Project description:The hepatic lipase gene (LIPC) is known to play an important role in lipid and lipoprotein metabolism pathways, but the association of the LIPC rs1532085 single nucleotide polymorphism (SNP) and serum lipid profiles has not been previously reported in different racial/ethnic groups. The present study was to detect the association of the LIPC rs1532085 SNP and several environmental factors with serum lipid levels in the Maonan and Han populations. Genotypes of the LIPC rs1532085 SNP in 833 individuals of Maonan nationality and 801 participants of Han nationality were determined by polymerase chain reaction and restriction fragment length polymorphism. The frequencies of AA, AG, and GG genotypes were 22.34%, 47.70%, and 29.96% in Han, and 24.96%, 51.38%, and 23.64% in Maonan populations (P < 0.05). The frequency of the G allele was 53.80% in Han and 49.33% in Maonan individuals (P < 0.05). The G allele carriers had lower total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), Apolipoprotein (Apo) A1 and ApoB levels in Han than the G allele non-carriers, but not in Maonan. Subgroup analyses indicated that the G allele carriers had lower TC, TG, LDL-C and ApoA1 levels in Han females than the G allele non-carriers (P < 0.05-0.001). Serum lipid parameters in the two ethnic groups were also associated with several environmental factors. These findings revealed that there might be a racial/ethnic- and/or sex-specific association between the LIPC rs1532085 SNP and serum lipid parameters in some populations.

Project description:BackgroundMaonan nationality belongs to a mountain ethnic minority in China. Little is known about the association of apolipoprotein A1 gene (APOA1) rs964184 single nucleotide polymorphism (SNP) and serum lipid levels in this population. The aim of this study was to detect the association of the APOA1 rs964184 SNP and several environmental factors with serum lipid profiles in the Chinese Maonan and Han populations.MethodsGenotypes of the APOA1 rs964184 SNP in 867 individuals of Maonan nationality and 820 participants of Han nationality were determined by polymerase chain reaction and restriction fragment length polymorphism, combined with gel electrophoresis, and confirmed by direct sequencing.ResultsThe frequencies of CC, CG and GG genotypes of the APOA1 rs964184 SNP were 68.86, 29.18 and 1.96% in the Maonan population, and 63.78, 30.85 and 5.37% in the Han population (P < 0.001). The frequency of the G allele was 16.55% in Maonan and 20.79% in Han (P < 0.001). The G allele carriers had lower high-density lipoprotein cholesterol (HDL-C) levels in Maonan and higher triglyceride (TG) levels in Han peoples than the G allele non-carriers. Subgroup analyses showed that the G allele carriers had lower HDL-C levels in both Maonan males and females; and lower apolipoprotein (Apo) A1 levels and the ApoA1/ApoB ratio in Han males than the G allele non-carriers. Serum lipid parameters in the two ethnic groups were also associated with several environmental factors.ConclusionsThe present study reveals that there may be a racial/ethnic- and/or gender-specific association between the APOA1 rs964184 SNP and serum lipid parameters in our study populations.Trial registrationRetrospectively registered.

Project description:The cytochrome P450 protein plays an important role in the synthesis of cholesterol and other lipid parameters. But little is known about the association of the single nucleotide polymorphism (SNP) of rs2068888 near cytochrome P450 26A1 gene (CYP26A1) and serum lipid profiles in the Chinese Maonan and Han populations. This study explored such association in the two populations. Genotyping of the CYP26A1 rs2068888 SNP was performed in 833 unrelated individuals of Maonan and 701 participants of Han by polymerase chain reaction and restriction fragment length polymorphism combined with gel electrophoresis, and confirmed by direct sequencing. The genotypic and allelic frequencies of the CYP26A1 rs2068888 SNP were significantly different between the Maonan and Han. The frequencies of AA, AG and GG genotypes were 75.51%, 23.41% and 1.08% in the Maonan population, and 64.62%, 33.10% and 2.28% in the Han population (P < 0.001). The frequency of the G allele was 12.78% in Maonan and 18.83% in Han (P < 0.001). The level of serum total cholesterol (TC) was lower in Maonan than in Han. The G allele carriers had higher serum TC level in Maonan than the G allele non-carriers. Subgroup analyses indicated that the G allele carriers had higher serum TC level in Maonan females. Serum lipid parameters in the two ethnic groups were also associated with several environmental factors. These findings revealed that there may be a racial/ethnic- and/or sex-specific association between the CYP26A1 rs2068888 SNP and serum lipid parameters in some populations.

Project description:The glycerol-3-phosphate acyltransferase mitochondrial gene (GPAM) variant has been associated with serum lipid levels in the Eurpean ancestry, but little is known about such association in Chinese populations. The aim of the present study was to investigate the relationship between the GPAM rs1129555 single nucleotide polymorphism (SNP) and several environment factors with blood lipid profiles in the Guangxi Maonan and Han populations. A total of 720 individuals of Maonan nationality and 780 participants of Han nationality were randomly selected from our previous stratified randomized samples. Genotyping of the rs1129555 SNP was carried out using the polymerase chain reaction-restriction fragment length polymorphism technique, and then confirmed by direct sequencing. The frequencies of C and T alleles were 72.85% and 27.15% in Maonan, and 65.19% and 34.81% in Han (P < 0.001); respectively. The frequencies of CC, CT, and TT genotypes were 51.53%, 42.36%, and 5.97% in Maonan, and 43.08%, 44.23%, and 12.69% in Han populations (P < 0.001). The T allele carriers had higher serum triglyceride (TG) in Han and higher low-density lipoprotein cholesterol (LDL-C) in both Maonan and Han than the T allele non-carriers (P < 0.05-0.01). Gender subgroup analyses showed that the T allele carriers had higher TG levels in Han males (P < 0.05) and higher LDL-C levels in Maonan males but not in famales (P < 0.01). Serum lipid parameters were also associated with several environmental factors (P < 0.05-0.001). These findings suggest that racial/ethnic- and/or gender-specific association occurs between the GPAM rs1129555 variant and serum lipid parameters in our study populations.

Project description:Little is known about the association of monoacylglycerol acyltransferase 1 gene (MGAT1) rs634501 single nucleotide polymorphism (SNP) and serum lipid profiles in the Chinese populations. The aim of this study was to detect the association of the MGAT1 rs634501 SNP and several environmental factors with serum lipid levels in the Chinese Maonan and Han populations. Genotypes of the SNP in 2014 unrelated participants (Han, 986; Maonan, 1028) were determined by polymerase chain reaction and restriction fragment length polymorphism combined with gel electrophoresis, and confirmed by direct sequencing. The genotypic and allelic frequencies of the MGAT1 rs634501 SNP were significantly different between the Han and Maonan populations as well as between males and females in the Maonan population. The A allele carriers had lower serum apolipoprotein (Apo) A1 levels, the ApoA1/ApoB ratio and higher ApoB levels in Maonans; and lower high-density lipoprotein cholesterol, ApoA1 levels, ApoA1/ApoB ratio, and higher triglyceride levels in Han than the A allele non-carriers. There were also different associations of the MGAT1 rs634501 SNP and serum lipid profiles between males and females in the both ethnic groups. Serum lipid parameters in the two ethnic groups were also associated with several environmental factors. These results suggest that the association of the MGAT1 rs634501 SNP and serum lipid parameters might have ethnic- and/or sex-specificity.

Project description:IntroductionThe Maonan population is a relatively isolated minority in China. Little is known about endothelial lipase gene (LIPG) single nucleotide polymorphisms (SNPs) and serum lipid levels in the Chinese populations. The present study aimed to detect the association of several LIPG SNPs and environmental factors with serum lipid levels in the Chinese Maonan and Han populations.MethodsIn total, 773 subjects of Maonan ethnicity and 710 participants of Han ethnicity were randomly selected from our previous stratified randomized samples. Genotypes of the LIPG rs2156552, rs4939883 and rs7241918 SNPs were determined by polymerase chain reaction-restriction fragment length polymorphism, and then confirmed by direct sequencing.ResultsThe allelic (rs2156552, rs4939883 and rs7241918) and genotypic (rs2156552 and rs4939883) frequencies were different between the two ethnic groups (p < 0.05-0.01). The minor allele carriers had lower apolipoprotein (Apo)A1/ApoB ratio (rs2156552 and rs7241918), high-density lipoprotein cholesterol (HDL-C) and apolipoprotein (Apo)A1 (rs2156552) levels and higher ApoB levels (rs4939883) in the Han population, and lower HDL-C (rs2156552, rs4939883 and rs7241918) levels in the Maonan minority than the minor allele non-carriers (p < 0.0167 after Bonferroni correction). Subgroup analyses according to sex showed that the minor allele carriers had a lower ApoA1/ApoB ratio (rs2156552 and rs7241918) and higher ApoB levels (rs7241918) in Han males, and lower ApoA1 and HDL-C levels in Maonan females than the minor allele non-carriers (p < 0.0167-0.001).ConclusionsThe present study demonstrates the association between the LIPG polymorphsims and serum lipid levels in the two ethnic groups. These associations might have an ethnic- and or/sex-specificity.

Project description:BackgroundThe current research was to assess the relationship of the solute carrier family 44 member 4 (SLC44A4) rs577272, notch receptor 4 (NOTCH4) rs3134931 SNPs and serum lipid levels in the Han and Maonan ethnic groups.MethodsThe genetic makeup of the SLC44A4 rs577272 and NOTCH4 rs3134931 SNPs in 2467 unrelated subjects (Han, 1254; Maonan,1213) was obtained by using polymerase chain reaction and restriction fragment length polymorphism technique, combined with gel electrophoresis, and confirmed by direct sequencing.ResultsThe genotype frequencies of SLC44A4 rs577272 and NOTCH4 rs3134931 SNPs were different between Han and Maonan populations (P < 0.05); respectively. The SLC44A4 rs577272 SNP was associated with total cholesterol (TC) and high-density lipoprotein cholesterol (HDL-C) levels in Maonan group. The NOTCH4 rs3134931 SNP was associated with triglyceride (TG) in Han; and TG and low-density lipoprotein cholesterol (LDL-C) levels in Maonan groups (P < 0.025-0.001). Stratified analysis according to gender showed that the SLC44A4 rs577272 SNP was associated with TC and HDL-C in Han and Maonan females; TC in Maonan males, meanwhile, the NOTCH4 rs3134931 SNP was associated with TG and HDL-C in Han males; TG in Han females; TG and LDL-C in Maonan males; and TG, HDL-C and LDL-C in Maonan females. Linkage disequilibrium analysis showed that the most common haplotype was rs577272G-rs3134931A (> 50%) in both Han and Maonan groups. The haplotype of rs577272G-rs3134931A was associated with TG and HDL-C in Han; and TC, TG and HDL-C in Maonan ethnic groups.ConclusionsThese results suggest that the relationship among SLC44A4 rs577272, NOTCH4 rs3134931 SNPs and serum lipid parameters may vary depending on the gender and/or ethnicity/race in some populations. Haplotypes could explain more changes in serum lipid parameters than any single SNP alone particularly for TC, TG and HDL-C.

Project description:BackgroundNiemann-pick C1-like 1 (NPC1L1) is a key protein for intestinal cholesterol transportation. Common single nucleotide polymorphisms (SNPs) in the NPC1L1 gene have been associated with cholesterol absorption and serum lipid levels. The present study was undertaken to explore the possible association of NPC1L1 rs2072183 1735 C > G SNP and several environmental factors with serum lipid levels in the Mulao and Han populations.MethodsGenotyping of the rs2072183 SNP was performed in 688 subjects of Mulao and 738 participants of Han Chinese. The interactions between NPC1L1 1735 C > G polymorphism and several environmental factors on serum lipid phenotypes were tested using the factorial design covariance analysis after controlling for potential confounders.ResultsThe frequency of G allele was lower in Mulao than in Han (29.72% vs. 37.26%, P < 0.001). The frequency of CC, CG and GG genotypes was 49.85%, 40.84% and 9.31% in Mulao, and 39.30%, 46.88% and 13.82% in Han (P < 0.001); respectively. The levels of low-density lipoprotein cholesterol (LDL-C), apolipoprotein (Apo) B and the ratio of ApoAI/ApoB in Han but not in Mulao were different among the three genotypes (P < 0.05 for all), the subjects with GG and CG genotypes had higher LDL-C, ApoB levels and lower ApoAI/ApoB ratio than the subjects with CC genotype. Subgroup analysis showed that the G allele carriers in Han had higher total cholesterol (TC), LDL-C and ApoB levels in males (P < 0.05) and lower ApoAI/ApoB ratio in both sexes (P < 0.05) than the G allele noncarriers. The G allele carriers in Mulao had higher TC and LDL-C levels in males (P < 0.05) and lower high-density lipoprotein cholesterol (HDL-C) levels in both sexes (P < 0.05) than the G allele noncarriers. Serum TC, LDL-C, ApoB levels and ApoAI/ApoB ratio were correlated with genotypes in Han males (P < 0.05) but not in females. Serum lipid parameters were also correlated with several environmental factors. The genotypes of rs2072183 SNP were interacted with gender or cigarette smoking to influence serum TC and HDL-C levels in Mulao, whereas the genotypes of rs2072183 SNP were interacted with several environmental factors to influence all seven lipid traits in Han (P < 0.05-0.01).ConclusionsThe present study suggests that the rs2072183 SNP in NPC1L1 gene and its association with serum lipid profiles are different between the Mulao and Han populations. The difference in serum lipid profiles between the two ethnic groups might partly result from different rs2072183 SNP or NPC1L1 gene-environmental interactions.

Project description:The association of ADP-ribosylation factor-like 15 (ARL15) rs6450176 single nucleotide polymorphism (SNP) and serum lipid profiles has never been studied in the Chinese population. The present study was undertaken to detect the association of ARL15 rs6450176 SNP and several environmental factors with serum lipid levels in the Jing and Han populations. Genotypes of the SNP were determined in 726 unrelated subjects of Jing nationality and 726 participants of Han nationality. The genotypic and allelic frequencies of the SNP in Jing but not in Han were different between males and females (P < 0.001 and P < 0.05; respectively). The G allele carriers in Han had lower serum total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) and apolipoprotein (Apo) B levels, and higher ApoA1/ApoB ratio than the G allele non-carriers (P < 0.05-0.01). The G allele carriers in Jing had lower serum TC, high-density lipoprotein cholesterol (HDL-C), ApoA1, ApoB levels and higher ApoA1/ApoB ratio than the G allele non-carriers (P < 0.05 for all). Subgroup analyses showed that the G allele carriers had lower TC and LDL-C levels in Han males; lower LDL-C and ApoB levels in Han females; lower ApoB levels and ApoA1/ApoB ratio in Jing males; and lower LDL-C levels in Jing females than the G allele non-carriers (P < 0.05-0.01). Multiple linear regression analysis showed that serum TC, LDL-C, ApoB levels and the ApoA1/ApoB ratio in Han; and TC, HDL-C and ApoA1 levels in Jing were correlated with the genotypes of the ARL15 rs6450176 SNP (P < 0.05-0.001). Serum lipid parameters were also associated with several environmental factors in both ethnic groups. These findings indicated that there may be a racial/ethnic- and/or sex-specific association of the ARL15 rs6450176 SNP and serum lipid levels.

Project description:The objective of the present study was to detect the association of the rs4731702 single nucleotide polymorphism (SNP) and serum lipid levels in the Guangxi Mulao and Han populations. A total of 727 subjects of Mulao and 740 subjects of Han Chinese were included. Serum low-density lipoprotein cholesterol (LDL-C) and apolipoprotein (Apo) B levels were higher in Mulao than in Han (P < 0.05). The T allele carriers had higher serum LDL-C and ApoAI levels in Mulao, whereas they had lower high-density lipoprotein cholesterol (HDL-C) levels and ratio of ApoAI to ApoB in Han (P < 0.05) than the T allele noncarriers. Subgroup analyses showed that the T allele carriers had higher HDL-C, LDL-C, and ApoAI levels in Mulao males and lower ApoAI levels and ratio of ApoAI to ApoB in Han males than the T allele noncarriers. The subjects with TT genotype in Han females also had higher total cholesterol, LDL-C, ApoAI, and ApoB levels than the subjects with CT or CC genotype. Serum lipid parameters were also correlated with several environmental factors in both ethnic groups. The differences in the association of KLF14 rs4731702 SNP and serum lipid levels between the two ethnic groups might partly result from different gene-environmental interactions.
