We studied five common polymorphisms of TGFB1 in relation to osteoporosis-related phenotypes in a population-based cohort of 2975 British women, but found no significant association with bone mass, bone loss, bone markers, or fracture.<\/jats:p>\n               <jats:p>Introduction: The gene encoding TGFB1 is a strong functional candidate for genetic susceptibility to osteoporosis. Several polymorphisms have been identified in TGFB1, and previous work has suggested that allelic variants of TGFB1 may regulate BMD and susceptibility to osteoporotic fracture.<\/jats:p>\n               <jats:p>Materials and Methods: We studied the relationship between common polymorphisms of TGFB1 and several osteoporosis-related phenotypes including BMD at the lumbar spine and femoral neck, measured by DXA; bone loss over a 6-year period; biochemical markers of bone turnover (urinary free deoxypyridinoline and free pyridinoline\/creatinine ratio and serum N-terminal propeptide of type 1 collagen), and fractures in a population-based study of 2975 women from the United Kingdom. Participants were genotyped for single nucleotide polymorphisms (SNPs) in the TGFB1 promoter (G-800A; rs1800468; C-509T; rs1800469), exon 1 (T29C; rs1982073 and G74C; rs1982073); and exon 5 (C788T; rs1800471) on PCR-generated fragments of genomic DNA. Haplotypes were constructed from genotype data using the PHASE software program, and genotypes and haplotypes were related to the phenotypes of interest using general linear model ANOVA, with correction for confounding factors including age, height, weight, menopausal status, hormone replacement therapy (HRT) use, physical activity score, and dietary calcium intake.<\/jats:p>\n               <jats:p>Results: The polymorphisms were in strong linkage disequilibrium, and four common haplotypes accounted for &amp;gt;95% of alleles at the locus. There was no association between individual SNPs and BMD, bone loss, or biochemical markers of bone turnover. Haplotype analysis showed a nominally significant association with femoral neck BMD (p = 0.042) and with incident osteoporotic fracture (p = 0.013), but these were not significant after correcting for multiple testing.<\/jats:p>\n               <jats:p>Conclusions: Common polymorphic variants of the TGFB1 gene did not influence BMD or bone loss in this population.<\/jats:p>","DOI":"10.1359\/jbmr.061016","type":"journal-article","created":{"date-parts":[[2006,10,24]],"date-time":"2006-10-24T13:28:47Z","timestamp":1161696527000},"page":"195-202","source":"Crossref","is-referenced-by-count":14,"title":["Large-Scale
