Fragile X syndrome is the most common monogenetic cause of inherited intellectual disability and syndromic autism spectrum disorder. Fragile X syndrome is caused by an expansion (full mutation ≥200 CGGs repeats, normal 10-45 CGGs) of the fragile X mental retardation 1 () gene, epigenetic silencing of the gene, which leads to reduction or lack of the gene's product: the fragile X mental retardation protein. In this cross-sectional study, we assessed general and pharmacotherapy knowledge (GK and PTK) of fragile X syndrome and satisfaction with education in neurodevelopmental disorders (NDDs) among senior medical students in Serbia (N=348), Georgia (N=112), and Colombia (N=58). A self-administered 18-item questionnaire included GK (8/18) and PTK (7/18) components and self-assessment of the participants education in NDDs (3/18). Roughly 1 in 5 respondents had correct answers on half or more facts about fragile X syndrome (GK>PTK), which ranged similarly 5-7 in Serbia, 6-8 in Georgia, and 5-8 in Colombia, respectively. No cohort had an average value greater than 9 (60%) that would represent passing score "cut-off." None of the participants answered all the questions correctly. More than two-thirds of the participants concluded that they gained inadequate knowledge of NDDs during their studies, and that their education in this field should be more intense. In conclusion, there is a major gap in knowledge regarding fragile X syndrome among senior medical students in these three developing countries. The finding could at least in part be generalized to other developing countries aimed toward increasing knowledge and awareness of NDDs and fostering an institutional collaboration between developed and developing countries.
脆性 X 综合征是最常见的遗传性智力障碍和综合征性自闭症谱系障碍的单基因病因。脆性 X 综合征是由脆性 X 智力低下 1 基因 () 的扩展(完全突变≥200 CGG 重复,正常 10-45 CGG)引起的,基因的表观遗传沉默导致基因产物的减少或缺乏:脆性 X 智力低下蛋白。在这项横断面研究中,我们评估了塞尔维亚(N=348)、格鲁吉亚(N=112)和哥伦比亚(N=58)的高年级医学生对脆性 X 综合征的一般和药物治疗知识(GK 和 PTK)以及对神经发育障碍(NDDs)教育的满意度。一份自我管理的 18 项问卷包括 GK(8/18)和 PTK(7/18)部分以及参与者对 NDDs 教育的自我评估(3/18)。大约五分之一的受访者对脆性 X 综合征的一半或更多事实有正确的答案(GK>PTK),在塞尔维亚、格鲁吉亚和哥伦比亚,这一比例分别为 5-7、6-8 和 5-8。没有一个队列的平均值大于 9(60%),这将代表及格分数“截止”。没有一个参与者回答了所有的问题正确。超过三分之二的参与者认为他们在学习期间获得了不足够的 NDDs 知识,他们应该在这个领域接受更深入的教育。总之,这三个发展中国家的高年级医学生对脆性 X 综合征的知识存在重大差距。这一发现至少可以部分推广到其他发展中国家,旨在增加对 NDDs 的认识和意识,并促进发达国家和发展中国家之间的机构合作。
