Pathological myopia, a severe form of myopia, is characterized by an extreme elongation of the eyeball, leading to various vision-threatening complications. It is broadly classified into two primary types: high myopia, which primarily involves an excessive axial length of the eye with potential for reversible vision loss, and degenerative myopia, associated with progressive and irreversible retinal damage.
Leveraging data from DisGeNET, reporting 184 genes linked to high myopia and 39 genes associated with degenerative myopia, we employed the GenePlexus methodology in conjunction with screening tests to further explore the genetic landscape of pathological myopia.
Our comprehensive analysis resulted in the discovery of 21 new genes associated with degenerative myopia and 133 genes linked to high myopia with significant confidence. Among these findings, genes such as ADCY4, a regulator of the cAMP pathway, were functionally linked to high myopia, while THBS1, involved in collagen degradation, was closely associated with the pathophysiology of degenerative myopia. These previously unreported genes play crucial roles in the underlying mechanisms of pathological myopia, thereby emphasizing the complexity and multifactorial nature of this condition. The importance of our study resides in the uncovering of new genetic associations with pathological myopia, the provision of potential biomarkers for early screening, and the identification of therapeutic targets.
病理性近视是一种严重的近视形式,其特征是眼球极度伸长,会导致各种威胁视力的并发症。它大致可分为两种主要类型:高度近视,主要涉及眼轴长度过长,存在可逆性视力丧失的可能性;退行性近视,与进行性和不可逆的视网膜损伤相关。
利用DisGeNET数据库中的数据,该数据库报告了184个与高度近视相关的基因和39个与退行性近视相关的基因,我们采用基因网络分析方法并结合筛选测试,进一步探索病理性近视的遗传图谱。
我们的综合分析发现了21个与退行性近视相关的新基因和133个与高度近视相关的基因,且具有较高的可信度。在这些发现中,诸如环磷酸腺苷(cAMP)途径调节剂ADCY4等基因在功能上与高度近视相关,而参与胶原蛋白降解的凝血酶敏感蛋白1(THBS1)与退行性近视的病理生理学密切相关。这些先前未报道的基因在病理性近视的潜在机制中起着关键作用,从而强调了这种病症的复杂性和多因素性质。我们研究的重要性在于发现了与病理性近视新的遗传关联,提供了早期筛查的潜在生物标志物,并确定了治疗靶点。
