This paper presents the case of a 14-year-old boy with Danon disease exhibiting exclusive cardiac involvement, initially suspected as hypertrophic cardiomyopathy. Significant deterioration raised suspicion of an alternative etiology. A clinical exome revealed a previously unreported likely pathogenic variant, :c.645_651del (p.LysAsnfs∗25), in hemizygous state, confirming the diagnosis of Danon disease.
本文介绍了一名14岁患有丹侬病的男孩的病例,该病例最初被怀疑为肥厚型心肌病,心脏是唯一受累器官。病情显著恶化引发了对另一种病因的怀疑。临床外显子组检测发现了一个半合子状态的此前未报道的可能致病变异:c.645_651del(p.LysAsnfs∗25),从而确诊为丹侬病。
