We describe two Hispanic brothers born to unrelated parents with van den Ende-Gupta syndrome (VDEGS), a distinctive combination of characteristic dysmorphic features, skeletal abnormalities, and cerebellar hyperplasia. This syndrome was previously delineated by van den Ende et al. [1992: Am J Med Genet 42:467-469] and Gupta et al. [1995: J Med Genet 32:809-812], with additional reports by Phadke et al. [1998: Am J Med Genet 77:16-18] and Bistritzer et al. [1993: Clin Genet 44:15-19]. This is the fifth report of VDEGS, which is characterized by blepharophimosis, narrow nose with hypoplastic alae nasi, hypoplastic maxilla, everted lower lip, slender and elongated hands and feet, arachnodactyly, self-limiting joint contractures, and distinctive skeletal findings. This report of affected siblings, and a previous report of double second cousins born to consanguineous parents [Bistritzer et al. [1993: Clin Genet 44:15-19]], suggests autosomal recessive inheritance. This brings to eight, the total number of reported cases, derived from six families, three of which are consanguineous. It is important to distinguish VDEGS from Marden-Walker syndrome (MWS) since both syndromes include blepharophimosis, arachnodactyly, and congenital contractures. Both syndromes are inherited in an autosomal recessive fashion, but VDEGS lacks severe mental retardation, serious brain malformations, microcephaly, failure to thrive, and severe joint limitation, which are consistently present in MWS. Of particular importance, MWS may be associated with cerebellar malformations such as Dandy-Walker malformation, while the brothers reported herein with VDEGS both demonstrated distinctive cerebellar enlargement, a new finding for this disorder. While, congenital contractures with arachnodactyly are features commonly seen in several other delineated syndromes, such as congenital contractural arachnodactyly (CCA) syndrome, characteristic facial features (blepharophimosis, narrow nose with ocular hypertelorism, prominent ears, and everted lower lip), distinguish VDEGS from other syndromes associated with CCA, including CCA.
我们描述了一对西班牙裔兄弟,他们的父母无血缘关系,患有范登恩德 - 古普塔综合征(VDEGS),其具有独特的特征性畸形面容、骨骼异常和小脑增生的组合。该综合征先前由范登恩德等人[1992年:《美国医学遗传学杂志》42:467 - 469]和古普塔等人[1995年:《医学遗传学杂志》32:809 - 812]进行了描述,法德克等人[1998年:《美国医学遗传学杂志》77:16 - 18]和比斯特里策等人[1993年:《临床遗传学》44:15 - 19]也有相关报道。这是关于VDEGS的第五篇报道,其特征包括睑裂狭小、鼻窄伴鼻翼发育不全、上颌骨发育不全、下唇外翻、手脚细长、蜘蛛指(趾)、自限性关节挛缩以及独特的骨骼表现。这篇关于患病兄弟姐妹的报道,以及之前一篇关于近亲父母生育的双重二级表亲的报道[比斯特里策等人[1993年:《临床遗传学》44:15 - 19]],提示为常染色体隐性遗传。至此,报道的病例总数达到八例,来自六个家族,其中三个家族是近亲家族。将VDEGS与马登 - 沃克综合征(MWS)区分开来很重要,因为这两种综合征都包括睑裂狭小、蜘蛛指(趾)和先天性挛缩。两种综合征均以常染色体隐性方式遗传,但VDEGS不存在严重智力发育迟缓、严重脑畸形、小头畸形、生长发育迟缓以及严重关节受限等情况,而这些在MWS中始终存在。特别重要的是,MWS可能与小脑畸形如丹迪 - 沃克畸形有关,而本文报道的患有VDEGS的兄弟均表现出独特的小脑增大,这是该疾病的一个新发现。虽然,先天性挛缩伴蜘蛛指(趾)是其他几种已描述综合征中常见的特征,如先天性挛缩性蜘蛛指(趾)(CCA)综合征,但特征性面部特征(睑裂狭小、鼻窄伴眼距增宽、耳朵突出和下唇外翻)将VDEGS与其他与CCA相关的综合征,包括CCA区分开来。
