概括
NR2F1中的致病变体会导致博世-邦斯特拉-施阿夫视力缩综合征 (BBSOAS). DNA结合域 (DBD) 的变异与更严重的症状有关,尽管许多特征随着时间的推移而改善.
科学领域:
- 遗传学和罕见疾病.
- 神经发育障碍 神经发育障碍
- 眼科医生 眼科 眼科
背景情况:
- 博世 - 邦斯特拉 - 沙夫视力缩综合征 (BBSOAS) 是一种罕见的神经发育障碍,与NR2F1基因的病原变异有关.
- 这种综合征表现出各种症状,包括智力障碍,发育迟缓和视力障碍.
- 关于BBSOAS的自然进展的信息有限.
研究的目的:
- 综合评估BBSOAS患者的表型和症状进展情况.
- 为了研究NR2F1基因内的基因型-表型相关性.
- 提供关于BBSOAS的自然过程的见解.
主要方法:
- 开发和分发了一份问卷,收集47名BBSOAS患者的表型和症状发展数据.
- 还收集了医疗文件和照片,以补充问卷数据.
- 基因型-表型相关性通过比较具有DNA结合域 (DBD) 和其他基因区域变异的个体的临床特征来分析.
主要成果:
- 常见的症状包括发育迟缓,低血压,视力缩,鼻,眼,自闭症特征和薄体.
- 在DNA结合域 (DBD) 中具有NR2F1变异的个体表现出更高的严重特征,如婴儿和非语言性.
- 诊断时的年龄在基因型组之间有显著差异,DBD变异与早期诊断相关.
- 总体而言,症状改善的报道比症状恶化更频繁.
结论:
- 该研究证实了BBSOAS的特征性临床特征,并突出了NR2F1DNA结合域变异与更严重的表型之间的关联.
- 有证据表明,BBSOAS症状可能会随着时间的推移而改善,而不是进展,这与典型的神经退行性疾病模式相反.
- 进一步的前性纵向研究是必要的,以最终了解疾病的进展.

495
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

5.6K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...
