概括
确诊为血清阴性肌痛性肌痛症 (SNMG) 的患者中有很大一部分实际上患有先天性肌痛性肌痛综合征 (CMS). 基因检测至关重要,因为对免疫疗法的反应并不排除CMS.
科学领域:
- 神经学 神经学
- 遗传学 是一个遗传学.
- 罕见疾病 罕见疾病
背景情况:
- 骨髓灰质炎 (MG) 是一种神经肌肉结合障碍,通常是由自身抗体引起的.
- 大约10%的MG病例是血清阴性 (SNMG).
- 遗传性疾病,如先天性肌痛综合征 (CMS),可以模仿SNMG,需要不同的治疗方法.
研究的目的:
- 确定被诊断患有血清阴性肌痛严重症 (SNMG) 的患者中先天性肌痛综合征 (CMS) 的比例.
- 确定与SNMG患者分子诊断相关的临床和人口因素.
主要方法:
- 在奥地利3个中心对50名成年SNMG患者进行了全外体测序 (WES).
- 在基因查之前,患者接受了全面的血清学测试,以排除常见的MG自身抗体.
- 分析了临床和人口统计数据,以寻找与分子诊断的关联.
主要成果:
- 在50名SNMG患者中,有7名 (14%) 通过WES接受了CMS的遗传诊断,其中CHRNE和RAPSN的变异.
- 在另外4个案例中,还发现了不确定的遗传发现.
- 患有CMS的患者往往有较早的发病年龄,但在纠正后,没有任何因素与分子诊断一致相关.
- 在一些CMS患者中观察到免疫疗法的反应,突出显示了潜在的误诊.
结论:
- 相当一部分的SNMG诊断是由于潜在的遗传条件,特别是CMS.
- 对免疫疗法的积极反应并不排除CMS诊断.
- 对血清阴性肌痛综合征的遗传检测对于准确的诊断和适当的治疗管理至关重要.

01:15Myasthenia Gravis: Diagnostic Tests
1.9K
Myasthenia gravis is an autoimmune condition affecting neuromuscular transmission, causing generalized weakness in skeletal muscles. Initial diagnoses rely on patients' signs, symptoms, and medical history. The challenge lies in distinguishing myasthenia from other muscular dystrophies. An important diagnostic feature is the significant improvement of symptoms after administering anticholinesterase inhibitors.

2.8K
Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which...

97.8K
The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.
