Alazami syndrome is an autosomal recessive disease characterized by primordial dwarfism, distinct dysmorphic features, and severe intellectual disability. Since it was first identified in a large consanguineous Arabic family in 2012, additional cases have not been published in the literature. We present a 2-year-old Northern European/Caucasian female with short stature, failure to thrive, and developmental delay. Whole exome sequencing (WES) identified two novel pathogenic variants in LARP7 (c.213_214dup and c.651_655del), indicating a diagnosis of Alazami syndrome. The case report describes a novel genotypic and phenotypic presentation of Alazami syndrome, contributing to the current knowledge of the condition as well as the expansion of differential diagnoses for growth restriction and intellectual disability.
阿拉扎米综合征是一种常染色体隐性疾病,其特征为原始侏儒症、独特的畸形特征和严重智力残疾。自2012年在一个庞大的近亲阿拉伯家庭中首次被发现以来,文献中尚未发表其他病例。我们报告了一名2岁的北欧/高加索女性,她身材矮小、发育不良且有发育迟缓问题。全外显子组测序(WES)在LARP7基因中发现了两个新的致病变异(c.213_214dup和c.651_655del),确诊为阿拉扎米综合征。该病例报告描述了阿拉扎米综合征一种新的基因型和表型表现,有助于增进对该病症的现有认识以及扩大对生长受限和智力残疾的鉴别诊断范围。
