several asthma susceptibility loci, including a region containing the vitamin d receptor (vdr) gene located at chromosome 12q, have been identified using genome-wide screens. our aim is to investigate the association between single nucleotide polymorphisms (snps) in vdr gene and asthma. one hundred one asthma patients and 206 healthy controls were enrolled in this study. genotypes were determin...

The aim of this study was to test for the possible association between vitamin D receptor (VDR) genetic variants and susceptibility to gallbladder cancer (GBC). A total of 291 GBC cases were recruited and 396 gender- and age-matched healthy volunteers were enrolled as controls. The VDR gene polymorphisms were determined in all subjects. The genotype and the allele frequencies of ApaI, BsmI, and...

The current study investigated the association between vitamin-D-receptor (VDR) genotypes with bone-mineral density (BMD) and its interaction with physical activity level (PAL). Individuals in a sample of 192 volunteers (67.84 +/- 5.23 years) underwent BMD evaluation and were genotyped for VDR ApaI, BsmI, FokI, and TaqI polymorphisms. Haplotypes were reconstructed through expectation-maximizati...

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 ...

Vitamin D deficiency is associated with several diseases including multiple sclerosis (MS). Several factors influence vitamin D levels and its optimal multi-function maintenance. Our objective was to assess quantifiable variables influencing vitamin D level and metabolism in MS patients from Kuwait. In a case-control study involving 50 MS patients, and 50 healthy control individuals for which p...

Aims. Studies on the associations of vitamin D receptor (VDR) gene polymorphisms with diabetic retinopathy (DR) susceptibility reported conflicting results. A systematic meta-analysis was undertaken to clarify this topic. Methods. A systematic search of electronic databases (PubMed, EMBASE, and CNKI) was carried out until March 31, 2016. The pooled odds ratio (OR) and 95% confidence interval (C...

OBJECTIVES Vitamin D receptor (VDR) gene plays an important role in bone mass regulation. We have previously shown a beneficial effect of vitamin D supplementation on bone mass in girls. This study investigated whether the musculo-skeletal response to Vitamin D was modulated by polymorphisms in VDR gene. DESIGN Randomized placebo-controlled trial. METHODS 179 girls (10-17 years), were rando...

OBJECTIVE : To investigate whether vitamin D receptor gene (VDR) BsmI-rs1544410 and FokI-rs2228570 polymorphisms, smoking duration, and body mass index (BMI) are risk factors for cutaneous melanoma, especially metastatic melanoma. METHODS : We studied 120 cutaneous melanoma cases [68 stage I and II non-metastatic melanoma (NMetM) patients, plus 52 Stage III and IV metastatic melanoma (MetM) p...
