Ehlers-Danlos syndrome (EDS) is a heritable connective tissue disorder characterized by a varying degree of skin hyperextensibility and joint hypermobility. EDS is classified into 13 subtypes according to the most recent classification. These subtypes are clinically and genetically heterogenous. The spondylodysplastic subvariety of EDS (spEDS) is caused by homozygous mutations in B4GALT7, B3GALT6 and SLC39A13. To date, 13 individuals with molecularly diagnosed SLC39A13-related spEDS have been reported. The spEDS caused by biallelic pathogenic SLC39A13 variants are characterized by short stature, protuberant eyes with bluish sclera, finely wrinkled palms, hypermobile joints, hyperextensible skin and characteristic radiological findings. Herein, we report a case of 7-year-old-female child with spEDS associated with novel homozygous (pathogenic/likely pathogenic) missense variation of the SLC39A13 gene.
埃勒斯-当洛综合征(EDS)是一种遗传性结缔组织疾病,其特征为不同程度的皮肤过度伸展性和关节活动过度。根据最新分类,EDS分为13个亚型。这些亚型在临床和遗传上具有异质性。EDS的脊柱发育不良亚型(spEDS)由B4GALT7、B3GALT6和SLC39A13的纯合突变引起。迄今为止,已报道了13例分子诊断为SLC39A13相关spEDS的个体。由双等位基因致病性SLC39A13变异引起的spEDS的特征为身材矮小、眼球突出且巩膜呈蓝色、手掌细纹、关节活动过度、皮肤过度伸展以及特征性影像学表现。在此,我们报告一例7岁女童患有与SLC39A13基因新型纯合(致病性/可能致病性)错义变异相关的spEDS。
