An electroencephalogram (EEG) revealed marked spike‐and‐wave activation during sleep (SWAS), although no clinically documented seizures were observed. The younger sister, who was 9 years old, displayed a similar clinical presentation, including spastic paraparesis with ataxia, microcephaly, dysmorphisms, however, she displayed slightly more severe intellectual deficits and polymorphic seizures. EEG revealed a SWAS pattern in this case. Magnetic resonance imaging scans in both cases showed only a thin corpus callosum. Whole exome sequencing unveiled the presence of two likely pathogenic variants in compound heterozygosity within the ALDH18A1 gene. Specifically, these variants included the splice site variant c.88 + 1c.88+1G>A of paternal origin and the variant c.1364c.1364T>C (p.Leu455Ser) of maternal origin. Both sisters displayed normal blood levels of ammonia, ornithine, citrulline, arginine, and other amino acids.These findings were compatible with ALDH18A1‐related HSP complicated with a clinical and EEG pattern reminiscent of DEE‐SWAS. We present the first report of DEE‐SWAS in ALDH18A1‐related HSP, expanding the clinical manifestations of this complex neurodevelopmental condition.","PeriodicalId":503206,"journal":{"name":"Annals of the Child Neurology Society","volume":"146 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139855676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
