Ehlers-Danlos syndromes (EDSs) are a group of rare monogenic conditions with strong heterogeneity and can be caused by 20 genes associating with the essence of the extracellular matrix (ECM). This study enrolled three cases with various subtypes of EDS. Clinical evaluation and genetic testing with whole-exome sequencing (WES) were performed. The clinical manifestations of all three patients were thoroughly monitored; and three de novo diagnostic variants, namely COL5A1: NM_001278074.1: c.4609-2A>C, COL3A1: NM_000090.3: c.3554G>T(p.Gly1185Val), and COL1A1: NM_000088.3: c.545G>T(p.Gly182Val) were identified from them, respectively. The findings in this study expanded the mutation spectrum of EDS and strengthened the efficiency of WES in the differential diagnosis on disorders with overlapping phenotypes and various pathogenesis.
埃勒斯-当洛斯综合征(EDS)是一组罕见的单基因疾病,具有很强的异质性,可由 20 个与细胞外基质(ECM)本质相关的基因引起。本研究纳入了 3 例具有不同亚型 EDS 的病例。进行了临床评估和全外显子组测序(WES)的基因检测。对所有 3 名患者的临床表现进行了彻底监测;并从他们中分别鉴定出三个新诊断的变异,即 COL5A1:NM_001278074.1:c.4609-2A>C、COL3A1:NM_000090.3:c.3554G>T(p.Gly1185Val)和 COL1A1:NM_000088.3:c.545G>T(p.Gly182Val)。本研究的结果扩展了 EDS 的突变谱,并加强了 WES 在具有重叠表型和多种发病机制的疾病的鉴别诊断中的效率。
