  • association of vitamin d receptor gene polymorphism with the urine calcium level in nephrolithiasis patients
    Journal of Receptors and Signal Transduction, 2015
    Co-Authors: Tianbiao Zhou, Zongpei Jiang, Miaofang Huang, Rui Zhang
    Abstract:

    AbstractAssociation of vitamin D receptor (VDR) gene polymorphism with the urine calcium level in nephrolithiasis patients from the published reports are still conflicting. This study was conducted to evaluate the relationship between VDR BsmI (rs1544410), Fok1 (rs2228570), TaqI (rs731236) and ApaI (rs7975232) gene polymorphism and urine calcium level in nephrolithiasis patients using meta-analysis method. The association studies were identified from PubMed, and Cochrane Library on 1 April 2014, and eligible investigations were included and synthesized using meta-analysis method. Four reports were recruited into this meta-analysis for the association of VDR BsmI, Fok1, TaqI and ApaI gene polymorphism with urine calcium level in nephrolithiasis patients. In this meta-analysis, VDR BsmI B allele and BB genotype, Fok1 f allele and ff genotype, TaqI, and ApaI gene polymorphism were not associated with urine calcium level in nephrolithiasis patients. However, the BsmI bb genotype and Fok1 FF genotype were asso...

    Abstract:

    Association of vitamin D receptor (VDR) gene polymorphism with the risk of nephrolithiasis from the published reports is still conflicting. This study was conducted to evaluate the relationship between VDR BsmI (rs1544410), Fok1 (rs2228570), TaqI (rs731236) and ApaI (rs7975232) gene polymorphism and the risk of nephrolithiasis using meta-analysis method. The association studies were identified from PubMed, and Cochrane Library on 1 April 2014, and eligible investigations were included and synthesized using meta-analysis method. Six reports were recruited into this meta-analysis for the association of VDR BsmI, Fok1, TaqI and ApaI gene polymorphism with nephrolithiasis susceptibility. In this meta-analysis, VDR BsmI, Fok1, TaqI and ApaI gene polymorphism were not associated with nephrolithiasis susceptibility for overall populations and in Caucasians. However, the Fok1 f allele and ff genotype were associated with the risk of nephrolithiasis in Asians, but the FF genotype not. Furthermore, TaqI TT genotype was associated with the risk of nephrolithiasis in Asians, but the t allele and tt genotype not. However, ApaI gene polymorphism was not associated with nephrolithiasis susceptibility in Asians. In conclusion, VDR BsmI, Fok1, TaqI and ApaI gene polymorphism were not associated with nephrolithiasis risk in overall populations and in Caucasians. But, the Fok1 f allele and ff genotype, TaqI TT genotype, ApaI gene polymorphism were associated with the risk of nephrolithiasis in Asians. However, more studies should be conducted to confirm it.

  • linkage disequilibrium analysis of the dopamine beta hydroxylase gene in persistent attention deficit hyperactivity disorder
    Psychiatric Genetics, 2004
    Co-Authors: Becky Inkster, Pierandrea Muglia, Umesh Jain, James L Kennedy
    Abstract:

    Numerous family, twin and adoption studies have reported a strong genetic component for attention deficit hyperactivity disorder (ADHD). In addition, an extensive amount of literature has implicated abnormalities of the dopaminergic system. In view of this evidence, genes that influence dopaminergic transmission have become prime candidates for molecular genetic investigations of ADHD. There are currently three studies (Daly et al., 1999; Roman et al., 2002; Wigg et al., 2002) that have found an association between the dopamine beta-hydroxylase gene (DBH) TaqI 2 allele and childhood ADHD. As such, we tested for association of the DBH TaqI 2 allele in two independent samples of patients with the persistent variant of ADHD. These consisted of 97 nuclear families, and 112 adult cases with controls carefully matched according to gender, age and ethnicity. Transmission Disequilibrium Test analysis revealed weak over-transmission of the 2 allele (35 transmissions versus 27 non-transmissions; chi2 = 1.03, 1 degree of freedom, P=0.31). The case-control sample did not support previous findings since the 2 allele was more frequent in our control sample (137 versus 116; chi2 = 3.63, 1 degree of freedom, P=0.057). Taken together, these results do not provide support for a role of the DBH TaqI marker in our persistent ADHD samples.

  • attention deficit hyperactivity disorder and the gene for dopamine beta hydroxylase
    American Journal of Psychiatry, 2002
    Co-Authors: Karen Wigg, Gwyneth Zai, Russell Schachar, Rosemary Tannock, Wendy Roberts, Molly Malone, James L Kennedy, Cathy L Barr
    Abstract:

    OBJECTIVE: Attention deficit hyperactivity disorder (ADHD) has been shown to be highly heritable, and recent molecular genetics studies have focused on candidate genes in the dopaminergic and noradrenergic systems. One recent study reported an association of an allele of the TaqI polymorphism located in the fifth intron of the gene for dopamine beta-hydroxylase (DBH). The authors’ goal was to replicate this finding. METHOD: The authors investigated the linkage of the alleles and haplotypes of three polymorphisms at the DBH locus in 117 nuclear families with ADHD. RESULTS: No significant evidence was found for linkage of the TaqI alleles or haplotypes in the 117 families. However, the authors observed some evidence for biased transmission of the same allele of the TaqI polymorphism, as previously reported. CONCLUSIONS: These findings suggest that the gene for DBH should be investigated further.

  • association of vitamin d receptor TaqI and apai genetic polymorphisms with nephrolithiasis and end stage renal disease a meta analysis
    BMC Medical Genetics, 2019
    Co-Authors: Tajamul Hussain, Shaik Mohammad Naushad, Anwar Ahmed, Salman Alamery, Arif Mohammed, Mohamed O Abdelkader, Nasser Abobakr Nasser Alkhrm
    Abstract:

    The deficiency of vitamin D receptor (VDR) or its ligand, vitamin D3, is linked to the development of renal diseases. The TaqI (rs731236) and ApaI (rs7975232) polymorphisms of VDR gene are widely studied for their association with renal disease risk. However, studies have largely been ambiguous. Meta-analysis was carried out to clarify the association of TaqI (2777 cases and 3522 controls) and ApaI (2440 cases and 3279 controls) polymorphisms with nephrolithiasis (NL), diabetic nephropathy (DN) and end stage renal disease (ESRD). The VDR TaqI C-allele under allele contrast was significantly associated with ESRD in both fixed effect and random effect models, and ApaI C-allele with ESRD only under fixed effect model. Cochrane Q-test showed no evidence of heterogeneity for TaqI polymorphism and a significant heterogeneity for Apa I polymorphism. No publication bias was observed for both the polymorphisms. The present meta-analysis identifies TaqI and ApaI polymorphisms of VDR gene as risk factors for renal diseases.
