Abstract Background The association between the vitamin D receptor ( VDR ) gene polymorphism and the risk of Multiple sclerosis (MS) has been evaluated in several studiese. However, the findings were inconsistent and inconclusive.Methods All relevant studies reporting the association between the FokI (rs2228570) or/and TaqI (rs731236) or/and BsmI (rs1544410) or/and ApaI (rs7975232) polymorphisms of the VDR and susceptibility to multiple sclerosis published up to September 2019 were identified by comprehensive systematic database search in web of science, Scopus, and PubMed.Results A total of 30 case–control studies were included in this meta-analysis. The overall results suggested a significant association between TaqI gene polymorphism and MS risk under heterozygote contrast (OR = 1.27, 95%CI = 1.01–1.59, REM). Moreover, the pooled results of subgroup analysis decline presence of significant association under all defined genotype model. In subgroup analysis, BsmI gene polymorphism was associated with increased risk of MS under the recessive model in Asian population. In other hand, ApaI gene polymorphism was associated with decreased risk of MS under recessive and homozygote contrast (aa vs AA) models in Asian population.Conclusions This meta-analysis suggested a significant association between TaqI gene polymorphism and MS susceptibility. Furthermore, BsmI gene polymorphism was associated with an increased risk of MS in Asian population. In contrast, ApaI gene polymorphism was associated with a decreased risk of MS in Asian population. Future large scale studies on gene–environment and gene– gene interactions are required to estimate related risk factors and assist early diagnosis of patients at high risk for MS.

Multiple studies have provided evidence for an association between reduced sun exposure and increased risk of multiple sclerosis (MS), an association likely to be mediated, at least in part, by the vitamin D hormonal pathway. Herein, we examine whether the vitamin D receptor ( VDR), an integral component of this pathway, influences MS risk in a population-based sample where winter sun exposure in early childhood has been found to be an important determinant of MS risk. Three polymorphisms within the VDR gene were genotyped in 136 MS cases and 235 controls, and associations with MS and past sun exposure were examined by logistic regression. No significant univariate associations between the polymorphisms, rs11574010 ( Cdx-2A > G), rs10735810 ( Fok1T >  C), or rs731236 ( Taq1C > T) and MS risk were observed. However, a significant interaction was observed between winter sun exposure during childhood, genotype at rs11574010, and MS risk ( P = 0.012), with the ‘G’ allele conferring an increased risk of MS in the low sun exposure group (≤2 h/day). No significant interactions were observed for either rs10735810 or rs731236, after stratification by sun exposure. These data provide support for the involvement of the VDR gene in determining MS risk, an interaction likely to be dependent on past sun exposure.

Abstract Background: Tuberculosis is one of the top ten causes of deaths worldwide. The deficiency of vitamin D was reported to be associated with the increased susceptibility of tuberculosis. Various previous reports were published to check the association of FokI polymorphism of the vitamin D receptor gene with tuberculosis risk. But their results were inconsistent so, we performed a meta-analysis to know the exact relation of the two.Methods: Different databases were screened up to November, 2020 with the keywords “Vitamin D receptor”, “VDR”, and “FokI”, along with “Tuberculosis” and “TB” to find the suitable articles. All the statistical analyses were performed by the Open Meta-Analyst program and all p-values were two-tailed with a significance level of 0.05.Results: No statistically significant association was observed in the allele contrast model (ORfvs.F= 1.11, 95%CI= 0.99-1.24, p= 0.05, I2= 73.46%), in the dominant model (ORff+Ffvs.FF= 1.11, 95%CI= 0.96-1.28, p= 0.14, I2= 71.39%), and in the co-dominant model (ORFfvs.FF= 1.05, 95%CI= 0.92-1.21, p= 0.41, I2= 65.97%). However, a significant association was found in the homozygote model (ORffvs.FF= 1.32, 95%CI= 1.03-1.69, p= 0.02, I2= 67.02%) and in the recessive model (ORFF+Ff vs.ff= 1.26, 95%CI= 1.03-1.54, p= 0.02, I2= 58.01%). Further analysis was performed on the bases of the ethnicity. In Asian population a significant association was found in the homozygote model (ORffvs.FF= 1.57, 95%CI= 1.12-2.21, p= 0.008, I2= 70.37%) and in the recessive model (ORFF+Ff vs.ff= 1.43, 95%CI= 1.08-1.89, p= 0.01, I2= 63.13%).Conclusion: In conclusion, a significant association of FokI with tuberculosis susceptibility was found in the overall analysis and in the Asian population.

Abstract Background Gestational diabetes mellitus (GDM) is a common disease during pregnancy. The association of vitamin D receptor (VDR) polymorphisms with GDM is still controversial. This study aimed to assess the associations between VDR polymorphisms and GDM risk. Methods We searched Cochrane Library, PubMed, and Embase electronic database for all eligible studies published from Jan 1, 1980 to December 31, 2020 to conduct a Meta-analysis. We analyzed four VDR polymorphisms: BsmI (rs1544410), ApaI (rs7975232), TaqI (rs731236), and FokI (rs2228570). Inclusion Criteria: (1) The data can be evaluated; (2) case–control study; and (3) meeting the Hardy–Weinberg’s law. Exclusion criteria: (1) Insufficient or extractable data; (2) Severe publication bias in the data; and (3) duplicate publications. We eventually included 15 studies in seven articles, including 2207 cases and 2706 controls. Results We eventually included 15 studies in seven articles, including 2207 cases and 2706 controls. The data showed that ApaI (rs7975232) VDR gene polymorphism was related with the risk of GDM for the comparison of CC vs AA and recessive model in overall population and FokI (rs2228570) VDR gene polymorphism was associated with the risk of GDM for recessive model in overall population. BsmI (rs1544410) polymorphism was not related with the risk of GDM in overall population. However, in the analysis of subgroups grouped by race, BsmI (rs1544410) has certain correlations. And, the data suggested the TaqI (rs731236) polymorphism was not associated with GDM. Conclusion Based on the meta-analysis, VDR ApaI (rs7975232) and FokI (rs2228570) polymorphisms increase susceptibility to GDM. In the future, it can be used to diagnose and screen molecular biomarkers for GDM patients.

Abstract It is still unclear whether there was an association between vitamin D receptor (VDR) gene polymorphism and systemic lupus erythematosus (SLE). This meta analysis including 19 studies were performed using Stata software. In our analysis, VDR ApaI polymorphism was correlated with SLE susceptibility in general populations (AA vs aa: P=0.003; AA+Aa vs aa: P=0.000). VDR gene ApaI and BsmI polymorphism were correlated with SLE susceptibility in Caucasian populations (BB vs Bb+bb: p=0.005; B vs b: P=0.026; AA vs aa: P =0.038). VDR BsmI and FokI polymorphism were correlated with SLE in African populations (BB+Bb vs bb: P=0.000; FF vs Ff +ff: P=0.000; F vs f: P=0.000; FF vs ff: P=0.000; FF+Ff vs ff: P=0.000). VDR ApaI polymorphism was correlated with SLE in Asian populations (AA+Aa vs aa) when stratified by race. Additionly, ApaI polymorphism was correlated with SLE in female subjects (AA vs aa: P =0.022) when stratified by gender. But there was no association between VDR TaqI polymorphism and SLE susceptibility in our analysis.

Background There have been studies focused on FokI, BsmI, ApaI and TaqI polymorphisms of the vitamin D receptor (VDR) gene and susceptibility to type 1 diabetes mellitus with controversial results. Methods This present study is a meta-analysis investigating the association between FokI, ApaI, TaqI and BsmI polymorphisms of VDR gene and type 1 DM in children. A literature search was performed using Medline, EMBASE, Cochrane and PubMed. Any study was considered eligible for inclusion if at least one of FokI, ApaI, TaqI and BsmI polymorphisms was determined, and outcome was type 1 DM at pediatric age. Results A total of 9 studies comprising 1053 patients and 1017 controls met the study inclusion criteria. The pooled odds ratios (ORs) of the FokI, ApaI, TaqI and BsmI polymorphisms were combined and calculated. Forest plots and funnel plots of the OR value distributions were drawn. Our meta-analysis has demonstrated statistically significant associations between DM1 and VDR genotypes, BsmIBB (P < 0.05), BsmIBb, (P < 0.05), BsmIbb (P < 0.05), TaqITT (P < 0.05) and TaqItt (P < 0.05) in children. Conclusion The results indicated that BsmIBB, BsmIBb and TaqItt polymorphisms were associated with an increased risk of type 1 DM, whereas BsmIbb and TaqITT had protective effect for type 1 DM in children.

BsmI (rs1544410) polymorphism located in intron 8 at the 3′-end of the vitamin D receptor (VDR) gene is known to be involved in the regulation of mRNA stability. Many studies evaluated the possible correlation between VDR BsmI polymorphism and the risk of pulmonary tuberculosis (PTB), and reported conflicting results. In the present study, an updated meta-analysis was performed to evaluate the above-said association. PubMed, Embase, and Google Scholar web-databases were searched for the relevant studies and a meta-analysis was performed by calculating pooled odds ratios (ORs) and 95% confidence intervals (95% CIs) for all the genetic models. A total of 19 studies comprising 3644 controls and 2635 cases were included in the present study. Overall no association of PTB in allelic contrast (b compared with B: P=0.285; OR =0.909, 95% CI =0.762–1.083), homozygous (bb compared with BB: P=0.881; OR =0.975, 95% CI =0.700–1.359), heterozygous (bB compared with BB: P=0.834; OR =1.017, 95% CI =0.872–1.185), dominant (bb compared with BB + Bb: P=0.451; OR =0.954, 95% CI =0.843–1.079) and recessive (bb + Bb compared with BB: P=0.983; OR =1.002, 95% CI =0.868–1.156) genetic models in comparison with wild-type allele and genotype BB were observed. However, variant allele (b compared with B: P=0.001; OR =2.289, 95% CI =1.661–3.154) showed increased risk of PTB in Asians. In conclusion, VDR BsmI polymorphism is not a risk factor for PTB in overall population. However, this polymorphism may be interrelated to an increased risk of PTB amongst Asians.

The association between vitamin D receptor (VDR) genetic polymorphism and lung cancer risk has been evaluated by the previous meta-analyses. Due to the emergence of novel studies and inappropriate inclusion of overlapping populations, an updated meta-analysis on recent evidences is necessarily needed. We comprehensively searched databases of PubMed, Web of Science and Chinese National Knowledge Infrastructure and finally obtained 7 eligible studies according to the inclusion criteria. Four positions on VDR gene, namely ApaI (rs7975232), BsmI (rs1544410), FokI (rs10735810) and TaqI (rs731236), were considered in this investigation. Data pooling found no significant association of lung cancer risk with ApaI or FokI. In contrast, it was indicated that the BsmI A allele was negatively related to the lung cancer risk, compared with the G allele (OR = 0.51, 95% CI = 0.33-0.79). Individuals with BsmI AA (OR = 0.53, 95% CI = 0.26-1.11) and AG genotypes (OR = 0.46, 95% CI = 0.30−0.71) showed decreased risk of lung cancer, compared with those of GG genotype. Regarding the TaqI polymorphism, the T allele carriers were at increased risk of lung cancer (OR = 1.25, 95% CI = 1.04-1.50). Compared with the TaqI TC+CC genotype, the TT genotype was positively associated with lung cancer risk (OR = 1.42, 95% CI = 1.11-1.82). No publication bias was identified in any of the analysis. In conclusion, VDR genetic polymorphism may be correlated to lung cancer risk. Given limited number of the included studies, more observations are warranted to draw a safer conclusion.

Abstract Purpose In the present study, we explored the link between vitamin D receptor (VDR) FokI gene polymorphisms with tuberculosis(TB). Methods Based on a comprehensive search of PubMed, Embase, Web of Science, Elsevier Science Direct, Cochrane Library, CNKI, Wanfang, and Chongqing VIP databases, we searched case-control study on FokI gene polymor-phism and TB susceptivity. The Newcastle-Ottawa Scale(NOS) was used to evaluate the quality of the literature and extracted data, and R 4.0.5 software was used for the meta-analysis. Results: Among the 243 selected articles, 35 in the meta analysis. The meta-analysis showed that the FokI gene polymorphism allene gene model(f vs F, Odds ratio=1.22,95% confidence interval:1.11-1.36); dominant model (ff+fF vs F, Odds ratio=1.29,95% confidence interval:1.13-1.47); recessive model(ff vs fF+FF, Odds ratio=1.31,95% confidence interval:1.09-1.56); codominant (ff vs FF, Odds ra-tio=1.48,95% confidence interval:1.19-1.83); codominant(fF vs FF, Odds ratio=1.23,95% confidence interval:1.09-1.39). The meta-analysis indicates a high level of heterogeneity between the VDR FokI gene polymorphism and TB and the race is a source of heterogeneity in the results. Conclusion The present update meta-analysis suggest that FokI gene polymorphism is significantly associated with an increased risk of TB.
