概括
这项研究发现,虽然USH2A变种导致了广泛的功能视力 (FV) 问题,但VALVVFQ-48工具可能无法完全捕捉Usher综合征2型 (USH2) 和自体逆性非综合性视网膜色素炎 (ARRP) 患者对日常活动的影响.
科学领域:
- 眼科医生 眼科 眼科
- 遗传学 遗传学 是一个
- 视觉科学科学 视觉科学
背景情况:
- USH2A基因变异与阿舍尔综合征2型 (USH2) 和自体逆性非综合性视网膜色素炎 (ARRP) 相关.
- 了解功能视觉 (FV) 对于评估这些遗传疾病对患者日常生活的影响至关重要.
研究的目的:
- 在双USH2A变异的患者中表征功能视力 (FV).
- 在研究开始时探索FV,视力敏度 (VA) 和视力丘 (V OT) 之间的相关性.
主要方法:
- 这是一项多中心,国际,横截面的研究,涉及121名具有双类USH2A变异的参与者.
- 通过听力学和病史证实了USH2或ARRP的临床诊断.
- VALVVFQ-48问卷是口服的,VA和VOT测量以评估功能视力.
主要成果:
- 功能视觉 (FV) 评分差异很大,从-2.0到7.6逻辑,ARRP和USH2组之间没有显著差异.
- 视力敏度 (VA) 和视力山峰 (V OT) 各解释了FV分数 (29%和26%分别) 的大量差异.
- 总的来说,VA和VOT占功能视觉观察到的变异的36%.
结论:
- 双性USH2A变体与广泛的功能视力障碍相关.
- 尽管USH2患者有听力损失,但FV结果在USH2和ARRP组之间是可比的.
- 修改后的VALVVFQ-48可能在充分评估USH2A相关视网膜退化对日常生活的影响方面存在局限性.

01:20The Retinoblastoma Gene
4.1K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

40.5K
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...

3.8K
Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...
