BACKGROUND Vitamin D deficiency has been associated with a multitude of disorders including diabetes, defective insulin secretion as well as rickets and poor bone health. Vitamin D is also a concern during childhood and adolescence and has been reported in girls from South Brazil. We determined the prevalence of vitamin D deficiency in girls from South Brazil and investigated whether the genoty...

Growing evidence suggests an elevated risk for colorectal neoplasia among individuals with low levels of vitamin D, the biological actions of which are mediated by the vitamin D receptor (VDR). To investigate the association among vitamin D status, VDR polymorphisms (FokI, and BsmI), and colorectal adenoma, we conducted a meta-analysis of nine studies of circulating levels of 25-hydroxyvitamin ...

The gene encoding vitamin D receptor (VDR) is recognized as a promising candidate for indicating the development of inflammatory bowel disease (IBD). Four genetic polymorphisms (ApaI, BsmI, FokI, TaqI) in VDR have been widely evaluated to determine their association with IBD, and the results of these evaluations are often inconsistent. Therefore, we conducted a meta-analysis to shed some light ...

Background: Vitamin D receptor (VDR) is present on adipocytes, and many studies were performed to investigate the association between polymorphisms in VDR gene with obesity. However, in the Arab Gulf populations, whereas obesity prevalence is increasing dramatically, only a few studies were addressed this relation with obesity based only on body mass index. This study aimed to find the associat...

The role of VDR gene BsmI (rs1544410) and FokI (rs10735810) polymorphisms in postmenopausal osteoporosis formation has been confirmed by the results fairly large number studies. However, pharmacogenetic aspects above have not adequately studied. aim this work is to study serum levels certain biochemical parameters, bone turnover markers, vitamin D parathyroid hormone women with dynamics treatme...

BACKGROUND The exact etiology of recurrent tonsillopharyngitis in children is not clear. Recurrent tonsillitis in children has multifactorial etiology like most of the diseases in childhood. In this study, our aim was to determine the potential role of vitamin D in recurrent tonsillitis by measuring serum 25-OH vitamin D levels and determining the vitamin D receptor polymorphism among children ...

Background: Small percentage of hepatitis C (HCV) patients develop hepatocellular carcinoma (HCC) during their lifetime, suggesting that genetic factors might modulate HCC development. Numerous variations on the vitamin D receptor gene (VDR) have been recognized in human cancers. The majority them cause VDR to be unable bind 1, 25-OH-D. aim present work was investigate relation FokI (rs2228570)...
