Purpose Colorectal cancer (CRC) is the third most common cancer and fourth leading cause of cancer mortality, and twin studies have shown that approximately 35% of the variation in susceptibility to CRC involves inherited genetic differences. We sought to investigate potential genetic associations between some single nucleotide polymorphisms (SNPs) and the risk of CRC in the Chinese Han population. Methods We conducted a case-control study including 269 cases and 309 controls. Sixteen SNPs associated with CRC risk were selected from previous genome-wide association studies and genotyped using Sequenom MassARRAY technology. Odds ratios and 95% confidence intervals (CIs) were calculated by unconditional logistic regression adjusting for age and gender. Results Using the chi-squared test we found that rs9365723 was associated with CRC risk (p = 0.012). With genetic model analysis, the genotype A/G-G/G (OR = 1.50; 95% CI 1.02-2.21; p = 0.038) of rs9365723 showed an increased risk of CRC in the dominant model. Furthermore, we found that rs9365723 was associated with an increased risk only for colon cancer but not rectal cancer (p = 0.009 and p = 0.414, respectively). Conclusions Our results, combined with previous studies, suggest that rs9365723, located on SYNJ2, is associated with the risk of CRC in a Chinese population. Thus, SYNJ2 may play a role in the development of CRC, especially colon cancer.

Abstract Background: As a main line of defense of the respiratory tract, the airway epithelium plays an important role in the pathogenesis of asthma. CDHR3 and EMSY were reported to be expressed in the human airway epithelium. Although previous genome-wide association studies found that the two genes were associated with asthma susceptibility, similar observations have not been made in the Chinese Han population. Methods: A total of 300 asthma patients and 418 healthy controls unrelated Chinese Han individuals were enrolled. Tag-single nucleotide polymorphisms (Tag-SNPs) were genotyped and the associations between SNPs and asthma risk were analyzed by binary logistic regression analysis. Results: After adjusting for confounding factors, the A allele of rs3847076 in CDHR3 was associated with increased susceptibility to asthma (OR = 1.407, 95% CI: 1.030-1.923). For the EMSY gene, the T alleles of both rs2508746 and rs12278256 were related with decreased susceptibility to asthma (additive model: OR = 0.718, 95% CI: 0.536-0.961; OR = 0.558, 95% CI: 0.332-0.937, respectively). In addition, the GG genotype of rs1892953 showed an association with increased asthma risk under the recessive model (OR = 1.667, 95% CI: 1.104-2.518) and the GATCTGAGT haplotype in EMSY was associated with reduced asthma risk ( P = 0.037). Conclusions: This study identified novel associations of rs3847076 in CDHR3 , as well as rs1892953, rs2508746 and rs12278256 in EMSY with adult asthma susceptibility in the Chinese Han population. Our observations suggest that CDHR3 and EMSY may play important roles in the pathogenesis of asthma in Chinese individuals. Further study with larger sample size is needed.

Forty-nine susceptible loci have been reported to be significantly associated with vitiligo by genome-wide association studies (GWASs) in European-derived whites. To date, some of these reported susceptibility loci have not yet been validated in the Chinese Han population. The purpose of this study was to examine whether the 16 reported susceptible loci in European-derived whites were associated with vitiligo in the Chinese Han population. Imputation was performed using our previous GWAS dataset by IMPUTE v2.2.2. The 16 imputed top single-nucleotide polymorphisms (SNPs) with suggestive signals, together with the reported SNPs, were genotyped in a total of 2581 patients and 2579 controls by the Sequenom MassARRAY system. PLINK 2.0 software was used to perform association analysis. The dbSNP database, HaploReg, and eQTL data were adopted to annotate the biological function of the SNPs. Finally, four SNPs from three loci were significantly associated with vitiligo, including rs3747517 (P = 1.29 × 10–3, OR = 0.87) in 2q24.2, rs4807000 (P = 7.78 × 10–24, OR = 0.66) and rs6510827 (P = 3.65 × 10–5, OR = 1.19) in 19p13.3, and rs4822024 (P = 6.37 × 10–10, OR = 0.67) in 22q13.2. According to the dbSNP database, rs3747517 is a missense variant of IFIH1, rs4807000 and rs6510827 are located in TICAM1, and rs4822024 is located 6 kb upstream of TEF. Further bioinformatics analysis by HaploReg and eQTL found that rs4807000, rs6510827, and rs4822024 are involved in regulating gene expression. Our study revealed the strong association of 2q24.2 (rs3747517), 19p13.3 (rs4807000, rs6510827), and 22q13.2 (rs4822024) with the risk of vitiligo in the Chinese Han population, which implicates common factors for vitiligo across different ethnicities, and helps expand the understanding of the genetic basis of this disease.

Background/Aims: The association between ACYP2(Acylphosphatase 2) polymorphisms and immunoglobulin A nephropathy (IgAN) risk in the Chinese Han population remains unclear. We aimed to evaluate the association between ACYP2 polymorphisms and IgAN risk by performing a case-control study. Methods: Eleven ACYP2 single nucleotide polymorphisms (SNPs) from 416 IgAN patients and 495 healthy controls were genotyped using the Sequenom MassARRAY platform. Odds ratio (OR) and 95% confidence interval (CI) were calculated to evaluate the association of ACYP2 polymorphisms with IgAN risk. Results: We observed that rs843720 was significantly associated with an increased risk of IgAN (allele G: OR = 1.23, 95% CI: 1.01–1.49, p = 0.036; dominant model: OR = 1.55, 95% CI: 1.01–2.37, p =0.044; log-additive model: OR = 1.43, 95% CI: 1.04–1.95, p = 0.026) before Bonferroni correction. The SNP rs12615793 was also significantly associated with an increased IgAN risk in the recessive model (OR = 3.33, 95% CI: 1.05–10.51, p = 0.042) before Bonferroni correction. Conclusion: These findings suggested that polymorphisms (rs843720 and rs12615793) of ACYP2 may be pivotal in the development of IgAN. However, more functional and association studies with larger sample sizes should be performed to further validate our results in the future.

ObjectivesSystemic sclerosis (SSc) is an uncommon autoimmune disease that varies with ethnicity. Single nucleotide polymorphisms (SNPs) in the GTFSI, NFKB1, and TYK2 genes have been reported to be associated with SSc in other populations and in individuals with various autoimmune diseases. This study aimed to investigate the association between these SNPs and susceptibility to SSc in a Chinese Han population.MethodA case-control study was performed in 343 patients with SSc and 694 ethnically matched healthy controls. SNPs in GTF2I, NFKB1, and TYK2 were genotyped using a Sequenom MassArray iPLEX system. Association analyses were performed using PLINK v1.90 software.ResultOur study demonstrated that the GTF2I rs117026326 T allele and the GTF2I rs73366469 C allele were strongly associated with patients with SSc (P = 6.97E-10 and P = 1.33E-08, respectively). Patients carrying the GTF2I rs117026326 TT genotype and the GTF2I rs73366469 CC genotype had a strongly increased risk of SSc (P = 6.25E-09 and P = 1.67E-08, respectively), and those carrying the NFKB1 rs1599961 AA genotype had a suggestively significantly increased risk of SSc (P = 0.014). Moreover, rs117026326 and rs73366469 were associated with SSc in different genetic models (additive model, dominant model, and recessive model) (P < 0.05) whereas rs1599961 was associated with SSc in the dominant genetic model but not in the addictive and recessive models (P = 0.0026). TYK2 rs2304256 was not significantly associated with SSc in this study.ConclusionGTF2I rs117026326 and rs73366469 SNPs were strongly associated with SSc in this Chinese Han population. NFKB1 rs1599961 showed a suggestive association with SSc, and no significant association was found between TYK2 rs2304256 and SSc in this Chinese Han population.

Background and Aim: Alcoholic Liver Disease (ALD), caused by longterm heavy alcohol consumption, is influenced by genetic factors. Studies have illustrated the overlapping genetic mechanism in Nonalcoholic Fatty Liver Disease (NAFLD) and ALD. Recently, a number of Genome-Wide Association Studies (GWAS) have demonstrated several SNPs were strongly associated with NAFLD. The aim of present study is to evaluate the association between these NAFLD-associated SNPs and ALD in Chinese Han population. Methods: Nine SNPs were selected and genotyped in a cohort of 507 patients with ALD and 645 healthy controls by using MassARRAY iPLEX system. Alleles and genotypes analysis of SNPs were performed in logistic regression. The association between SNP and the level of liver serum biomarkers was tested in chi-square test and linear regression model. Results: Our data confirmed that rs2281135 A-allele in PNPLA3 and rs3761472 G-allele in SAMM50 were significantly associated with increased risk of ALD (P = 1.93×10-12, OR [95% CI] = 1.82 [1.54-2.15]; P = 2.08×10-16, OR [95% CI] = 1.06 [1.04-1.08], respectively). The genotypes of rs2281135 were associated with ALD in additive, dominant and recessive genetic model (P = 1.24×10-11, P = 1.46×10-7, P = 2.07×10-9, respectively). In addition, rs2281135 was found to be associated with serum elevated levels of ALT (P = 5.0×10-3), AST (P = 0.03), ALP (P = 0.02), GGT (P = 0.03) in patients with ALD. Conclusions: The present study confirmed that PNPLA3 common variant rs2281135 was significantly associated with ALD in Chinese male Han population.

Abstract A limited number of genome-wide association studies (GWAS) have shown that CACNA1C is a potential candidate gene for insomnia. The present study sought to investigate the association of CACNA1C gene polymorphisms and insomnia in a Chinese Han population. Twenty-one single nucleotide polymorphisms (SNPs) in the CACNA1C were genotyped by using matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) with a Sequenom MassARRAY system in 205 patients with insomnia and 154 healthy controls. Data from all participants were systematically collected. Association of the polymorphisms with insomnia was evaluated by statistical analysis. Linkage disequilibrium (LD) and haplotype analysis were performed with Haploview v4.2 software. After adjustment for multiple comparisons and gender, age, body mass index (BMI), hypertension and glycated hemoglobin (HbA1c), only the rs2302729 in the recessive model (adjusted odds ratio [AOR]= 0.414, 95%CI= 0.220-0.771, P= 0.004) related to insomnia achieved significance by the false discovery rate (FDR) Benjamini and Hochberg (BH) criterion. The haplotypes rs2302729-rs1051375, CA and TG were significantly associated with insomnia (P<0.05). Our findings contributed important evidence for the confirming of CACNA1C as a susceptibility gene for insomnia in the samples of Chinese Han population.

Recent genome-wide association studies (GWAS) have indicated an association of histone deacetylase 9 (HDAC9) genetic variant with large-vessel stroke and coronary artery disease, among the European population. However, whether HDAC9 gene is associated with an increased susceptibility to acute coronary syndrome (ACS) in Chinese Han population is not known. A total of 472 patients, including patients with ACS (N=309), and those with chest pain syndrome (controls,N=163) were enrolled. Genotyping for HDAC9 gene was performed using the ligation detection reaction assay. A series of statistical analyses were performed to investigate the correlation between HDAC9 gene SNPs and the susceptibility to ACS. The results revealed a significant association of rs2240419 with ACS risk in which the A allele (P= 0.047) and the A allele carriers (AA + AG) (P= 0.037) were more likely to be in ACS group as compared to those in the control group. None of two other SNPs, rs2389995 and rs2107595, were significantly associated with ACS risk (P> 0.05). Logistic regression analyses further revealed an increased risk for ACS in A allele carrier among rs2240419 genotypes, as compared to those with GG homozygotes (odds ratio: 1.869, 95% CI 1.143, 3.056,P= 0.013). A significant correlation between rs2240419 polymorphism of HDAC9 gene and the susceptibility to ACS in Chinese Han population was observed in this study.
