Abstract

BACKGROUND:

SOX6 has been recently proposed as a pleiotropic gene for obesity and osteoporosis. The aim of this study was to investigate whether the rs7117858 genetic variant in SOX6 was associated with bone mass assessed by quantitative ultrasound (QUS) and obesity-related measures in a population of young adults.

METHODS:

A cross-sectional study was conducted in 550 unrelated healthy individuals of Caucasian ancestry (381 (69.3%) female and 169 (30.7%) male; mean age 20.46 ± 2.69). Bone mass was assessed through calcaneal QUS) parameter (BUA, dB/MHz). Obesity-related traits including weight, body mass index (BMI), fat mass (FM) and fat-free mass (FFM) were analysed.

RESULTS:

The linear regression analysis revealed that the rs7117858 SNP was significantly associated with FFM after adjustments for covariables in the whole sample (P = 0.027, β (95% CI) = 0.053 (0.092, 1.516). In addition, a significant association with QUS measurement adjusted for confounding factors was found in females (P = 0.043, β (95% CI) = 0.104 (0.138. 8.384).

CONCLUSIONS:

We demonstrate for the first time that SOX6 influence FFM and QUS trait in a population of young adults, suggesting the implication of this gene in obesity and osteoporosis-related phenotypes during early adulthood.
