The third patient of ACACA-related acetyl-CoA carboxylase deficiency with seizure and literature review

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.
