Low bone mass and osteopenia have been described in the axial and peripheral skeleton of patients with adolescent idiopathic scoliosis (AIS). Recently, many studies have shown that gene polymorphism is related to osteoporosis. However, no studies have linked the association between IL6 gene polymorphism and bone mass in AIS. This study examined the association between bone mass and IL6 gene polymorphism in 198 girls with AIS. The polymorphisms of IL6-597 G→A, IL6-572 G→C and IL6-174 G→A and the bone mineral density in the lumbar spine and femoral neck were analysed and compared with their levels in healthy controls. The mean bone mineral density at both sites in patients with AIS was decreased compared with controls (p = 0.0022 and p = 0.0013, respectively). Comparison of genotype frequencies between AIS and healthy controls revealed a statistically significant difference in IL6-572 G→C polymorphism (p = 0.0305). There was a significant association between the IL6-572 G→C polymorphism and bone mineral density in the lumbar spine, with the CC genotype significantly higher with the GC (p = 0.0124) or GG (p = 0.0066) genotypes. These results suggest that the IL6-572 G→C polymorphism is associated with bone mineral density in the lumbar spine in Korean girls with AIS.
The incidence of acute and chronic conditions
of the tendo Achillis appear to be increasing. Causation is multifactorial
but the role of inherited genetic elements and the influence of
environmental factors altering gene expression are increasingly
being recognised. Certain individuals’ tendons carry specific variations
of genetic sequence that may make them more susceptible to injury.
Alterations in the structure or relative amounts of the components
of tendon and fine control of activity within the extracellular
matrix affect the response of the tendon to loading with failure
in certain cases. This review summarises present knowledge of the influence of
genetic patterns on the pathology of the tendo Achillis, with a
focus on the possible biological mechanisms by which genetic factors
are involved in the aetiology of tendon pathology. Finally, we assess
potential future developments with both the opportunities and risks
that they may carry. Cite this article:
