Sumario:BACKGROUND: Association of genetic polymorphisms in paired box 1 (PAX-1) gene can influence the development of adolescent idiopathic scoliosis (AIS). PAX-1 is mainly expressed in the region of the vertebral bodies and intervertebral discs, being important for the proper formation of spinal structures. OBJECTIVES: The objective of this study was to evaluate the association of polymorphisms in PAX-1 gene with the susceptibility of AIS. SETTINGS AND DESIGN: This was an analytical observational case–control study. MATERIALS AND METHODS: Samples of 59 AIS indicated for surgical treatment, and 119 controls, without spinal disease were genotyped for PAX-1 rs6137473 and rs169311 polymorphisms. STATISTICAL ANALYSIS: The association of the polymorphisms with AIS was evaluated by a multivariable logistic regression model, using odds ratios (OR) and 95% confidence intervals (CI). RESULTS: According to Lenke's classification, 89.8% had Type I and 10.2% II curves. The mean value of the Cobb angle of the proximal thoracic curve was 30.8°, 58.7° thoracic, and 30.4° for the lumbar and on the bending films 14.6°, 40.7°, and 11°, respectively. Among the AIS group, there was a predominance of females (8.8:1). The PAX-1 rs169311 and rs6137473 polymorphisms were positively associated with developing the AIS (OR = 1.98; 95% CI = 1.2–3.3 and OR = 3.16; 95% CI = 1.4–7.3, respectively). The rs6137473 polymorphism was associated with the lumbar modifier B and C compared to A (OR = 2.52; 95% CI = 1.1–5.8). CONCLUSIONS: PAX-1 polymorphisms were associated with an increased risk of developing the AIS and with curve severity and can be used as a biomarker to map the risk of developing surgical-grade AIS, guiding the treatment of patients.
