The diagnosis of inherited neuromuscular disorders is challenging due to their genetic and phenotypic variability. Traditionally, neurophysiology and histopathology were primarily used in the initial diagnostic approach to these conditions. Sanger sequencing for molecular diagnosis was less frequently utilized as its application was a time-consuming and cost-intensive process. The advent and accessibility of next-generation sequencing (NGS) has revolutionized the evaluation process of genetically heterogenous neuromuscular disorders. Current NGS diagnostic testing approaches include gene panels, whole exome sequencing (WES), and whole genome sequencing (WGS). Gene panels are often the most widely used, being more accessible due to availability and affordability. In this mini-review, we describe the benefits and risks of clinical genetic testing. We also discuss the utility, benefits, challenges, and limitations of using gene panels in the evaluation of neuromuscular disorders.
由于遗传性神经肌肉疾病的遗传和表型变异性,其诊断具有挑战性。传统上,神经生理学和组织病理学主要用于这些疾病的初始诊断方法。用于分子诊断的桑格测序较少被使用,因为其应用是一个耗时且成本高昂的过程。下一代测序(NGS)的出现和可及性彻底改变了对基因异质性神经肌肉疾病的评估过程。当前的NGS诊断测试方法包括基因panel、全外显子组测序(WES)和全基因组测序(WGS)。基因panel通常是使用最广泛的,由于其可用性和可承受性而更容易获得。在这篇小型综述中,我们描述了临床基因检测的益处和风险。我们还讨论了在评估神经肌肉疾病中使用基因panel的实用性。益处、挑战和局限性。
