WTAP Gene Variants Confer Hepatoblastoma Susceptibility: A Seven-Center Case-Control Study.

ABSTRACT: Hepatoblastoma is a rare disease, and its etiology remains to be revealed. Wilms tumor suppressor-1-associated protein (WTAP) plays a critical role in tumorigenesis. However, whether single nucleotide polymorphisms (SNPs) of the WTAP gene predispose to hepatoblastoma risk awaits to be investigated. With the use of the TaqMan assay, we evaluated the genotype frequencies of three WTAP SNPs (rs7766006 G > T, rs9457712 G > A, and rs1853259 A > G) in Chinese children with 313 hepatoblastoma patients and 1,446 controls. Among these three SNPs, only the rs7766006 T allele exhibited a significant association with hepatoblastoma risk (GT versus GG: adjusted odds ratio [OR] = 0.70, 95% confidence interval [CI] = 0.53-0.92, p = 0.009; GT/TT versus GG: adjusted OR = 0.73, 95% CI = 0.57-0.95, p = 0.017). Combined analysis indicated that subjects with two risk genotypes showed significantly higher hepatoblastoma risk, compared to individuals without a risk genotype (adjusted OR = 1.38, 95% CI = 1.02-1.88, p = 0.037). The stratified analysis revealed that the rs1853259 GG genotype, the rs7766006 GT/TT genotype, and two risk genotypes modified hepatoblastoma risk in certain subgroups. The significant results were validated by haplotype analyses and false-positive report probability analyses. Furthermore, the expression quantitative trait locus analysis indicated that rs7766006 T was associated with decreased expression of WTAP mRNA. Collectively, our results suggest that WTAP SNPs may be genetic modifiers for the development of hepatoblastoma.

Project description:Background: Endometriosis is a common chronic gynecologic disorder with a significant negative impact on women's health. Wilms tumor 1-associated protein (WTAP) is a vital component of the RNA methyltransferase complex for N6-methyladenosine modification and plays a critical role in various human diseases. However, whether single nucleotide polymorphisms (SNPs) of the WTAP gene predispose to endometriosis risk remains to be investigated. Methods: We genotyped three WTAP polymorphisms in 473 ovarian endometriosis patients and 459 control participants using the Agena Bioscience MassArray iPLEX platform. The logistic regression models were utilized to assess the associations between WTAP SNPs and the risk of ovarian endometriosis. Results: In the single-locus analyses, we found that the rs1853259 G variant genotypes significantly increased, while the rs7766006 T variant genotypes significantly decreased the association with ovarian endometriosis risk. Combined analysis indicated that individuals with two unfavorable genotypes showed significantly higher ovarian endometriosis risk (adjusted OR = 1.71 [1.23-2.37], p = 0.001) than those with zero risk genotypes. In the stratified analysis, the risk effect of the rs1853259 AG/GG and rs7766006 GG genotypes was evident in subgroups of age ≤30, gravidity≤1, parity≤1, rASRM stage I, and the rs7766006 GG genotype was associated with worse risk (adjusted OR = 1.64 [1.08-2.48], p = 0.021) in the patients with rASRM stage II + III + IV. The haplotype analysis indicated that individuals with GGG haplotypes had a higher risk of ovarian endometriosis than wild-type AGG haplotype carriers. Moreover, false positive report probability and Bayesian false discovery probability analysis validated the reliability of the significant results. The quantitative expression trait loci analysis revealed that rs1853259 and rs7766006 were correlated with the expression levels of WTAP. Conclusion: Our findings demonstrated that WTAP polymorphisms were associated with susceptibility to ovarian endometriosis among Chinese women.
