带有眼部并发症的面纤维发育不良症 (CFD) 是由体质GNAS基因变异引起的,而不是遗传因素. 整体外基因组测序 (WES) 能够有效地检测到骨损伤中的这些变体,以便早期诊断.
科学领域:
- 遗传学 是一个遗传学.
- 眼科医生 眼科 眼科
- 病理学 病理学 病理学
背景情况:
- 面纤维发育不良症 (CFD) 是一种罕见的遗传疾病,其特征是用纤维组织取代骨.
- 眼部并发症可以显著影响CFD患者的视力和生活质量.
研究的目的:
- 在患有眼部并发症的患者中概述面纤维发育不良 (CFD) 的临床特征.
- 为了确定有效的早期诊断方法CFD与眼部参与.
主要方法:
- 招募了9名患有眼部并发症的CFD患者及其父母.
- 进行了眼睛,全身和骨损伤检查.
- 在骨损伤和外周血液上进行全外体序列测量 (WES),随后进行桑格序列验证和三组分析.
主要成果:
- 基于临床,放射和病理发现的CFD诊断. 主要症状包括视力下降 (100%),面形 (33%) 和偏视 (22%).
- 在所有骨病变中确定了体质GNAS基因变异 (c.601C>T:p.R201C和c.602G>A:p.R201H). (通过WES检测100%).
- 发现的GNAS变异在患者和父母的外周血液中不存在,证实了非遗传性和体质突变.
结论:
- 在CFD患者中,视通道或状鼻干扰的眼部症状需要考虑.
- 确定的CFD不是遗传的;体质GNAS基因变异是主要原因.
- WES是CFD的可行和有效的诊断工具,特别是用于检测骨损伤的体变异.
