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.
