Single‐nucleotide polymorphism in Turkish patients with adolescent idiopathic scoliosis: Curve progression is not related with MATN‐1, LCT C/T‐13910, and VDR BsmI

The role of genetics in the etiopathogenesis of adolescent idiopathic scoliosis (AIS) is unclear. In this study, we investigated the relationship between AIS and polymorphisms in MATN‐1, LCT C/T‐13910, and VDR BsmI genes. 53 Turkish adolescents with diagnosed AIS and 54 healthy adult individuals were included in the study. MATN‐1, LCT C/T‐13910, and VDR BsmI gene mutations were analyzed with real‐time PCR. We did not detect a statistically significant difference between AIS and control groups in respect to those three different gene polymorphisms ( p  < 0.05). We next evaluated the associations of all three SNPs with scoliosis curve severity. There was no significant difference between curve severity and gene polymorphisms ( p  < 0.05). In terms of gene polymorphisms, AIS patients with a family history of AIS did not significantly differ from AIS patients who did not have history ( p  < 0.05). AIS might be caused by many different gene mutations, biomechanical mechanisms that have been modified by environmental factors, different biological interactions, modulation of growth, or a synergy of different factors causing abnormal control of growth. However, the existing knowledge is still not enough to explain the etiopathogenesis of AIS. © 2012 Orthopaedic Research Society. Published by Wiley Periodicals, Inc. J Orthop Res 30:1459–1463, 2012
