title: Polymorphism in LRP5 (rs556442) is associated with higher TG levels in Iranian children.
abstract: BACKGROUND
  Wnt signalling/LRP5 is involved in adipogenesis by down-regulating adipogenic transcription factors. Therefore polymorphisms in components of this pathway may lead to metabolic disorders.
  
  
  OBJECTIVE
  This study tested the impact of LRP5 polymorphism on lipid profile in Iranian children.
  
  
  METHODS
  The study population was comprised of 9-18 year old children (125 boys, 137 girls). Total cholesterol (TC), High Density Lipoprotein (HDL), Low-Density Lipoprotein (LDL), Non-HDL cholesterol and Triglyceride (TG) levels were checked. Body composition was measured by the Hologic system DXA. PCR/restriction fragment length polymorphism (RFLP) was done for LRP5 (rs556442) genotyping. Multiple association analyses for TG level and genotype frequencies were assessed using logistic regression analysis, with adjustment for age, sex, BMI and puberty.
  
  
  RESULTS
  The results revealed that LRP5 (rs556442) had a significant influence on TG levels in unadjusted analysis and when adjusted for interacting factors. Higher TG levels were observed in AA/AG genotype of rs566442 in comparison to GG genotype (OR = 2.028, 95% CI = 0.997-4.127, p =  0.049).
  
  
  CONCLUSIONS
  It is concluded that allele A has an important impact on increasing TG level in LRP5 in the studied population.
