Hypothesis
Genetic polymorphisms in steroidogenesis enzyme genes may affect circulating sex steroid levels and thus influence the risk of high myopia.
Conclusion
Testosterone levels correlate with high myopia, and interaction of steroidogenesis enzyme genes and sex may be a modulating factor in sex hormone metabolism and high-myopia risk.
Supporting Evidence
- Testosterone levels were significantly higher in high-myopia cases compared to controls.
- Synergistic interaction between specific SNPs and sex was found to confer susceptibility to high myopia.
- Significant differences in hormone levels were observed between high-myopia cases and controls.
Takeaway
This study found that certain genes related to hormones might affect the risk of developing high myopia, especially in people with higher testosterone levels.
Methodology
The study involved 283 high-myopia cases and 280 controls, measuring hormone levels and genotyping SNPs in steroidogenesis enzyme genes.
Potential Biases
Potential biases include selection bias due to the campus-based sample and confounding factors related to lifestyle and genetics.
Limitations
The study's findings may not be generalizable beyond the Taiwanese population and may be influenced by unmeasured confounders.
Participant Demographics
Participants were Taiwanese individuals of Han Chinese origin, including 145 males and 138 females in the high-myopia group.
