Pathogenic variants in ACACA are the cause of acetyl-CoA carboxylase deficiency with an autosomal recessive inheritance that is identified by hypotonia, motor, and intellectual developmental delay. In this article, we describe a seven-year-old boy who is the child of consanguineous parents with a homozygous variant in ACACA (NM_198834.3:c.6641C > A, p.P2214H) that was detected by Whole-Exome Sequencing and confirmed by Sanger sequencing. This is the first reported patient of acetyl-CoA carboxylase deficiency that results from a homozygous pathogenic variant in the ACACA gene in the Iranian family. The proband presents with motor and intellectual developmental delay, muscle weakness, language disorder, facial dysmorphism, and poor growth. The patient discussed here is similar to other patients that were previously published; however, we were able to identify seizure that has hitherto not been reported. This paper describes the third person with a novel variant in the ACACA gene in the world that accounts for acetyl-CoA carboxylase deficiency and implicates the clinical spectrum of the disease. Finally, we describe an individual-based review of the symptoms associated with acetyl-CoA carboxylase deficiency. So far, only two acetyl-CoA carboxylase deficiency patients have been reviewed in the literature.
ACACA基因的致病性变异是导致常染色体隐性遗传的乙酰辅酶A羧化酶缺乏症的原因,其特征为肌张力减退、运动和智力发育迟缓。在本文中,我们描述了一名7岁男孩,他是近亲结婚父母的孩子,通过全外显子组测序检测到ACACA基因(NM_198834.3:c.6641C>A,p.P2214H)存在纯合变异,并经桑格测序确认。这是伊朗家族中首例因ACACA基因纯合致病性变异导致的乙酰辅酶A羧化酶缺乏症患者报告。先证者表现为运动和智力发育迟缓、肌肉无力、语言障碍、面部畸形和生长发育不良。本文讨论的患者与之前发表的其他患者相似;然而,我们发现了此前未报告过的癫痫症状。本文描述了世界上第三例携带ACACA基因新变异导致乙酰辅酶A羧化酶缺乏症的患者,并阐述了该疾病的临床谱系。最后,我们对与乙酰辅酶A羧化酶缺乏症相关的症状进行了基于个体的综述。到目前为止,文献中仅对两名乙酰辅酶A羧化酶缺乏症患者进行过综述。
