ABSTRACT

BACKGROUND: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that is now recognized to involve autonomic dysfunction. The burden of autonomic dysfunction is an important factor in the quality of life and prognosis of ALS patients. This article presents the clinical characteristics of a young female ALS patient with a fused in sarcoma (FUS) gene mutation and notable hyperhidrosis. METHOD: Detailed clinical characteristics of the patients were collected, and comprehensive examinations such as electrophysiological assessment, neuro-ultrasound, genetic testing, and relevant blood tests were conducted. RESULT: A 24-year-old female experienced progressive weakness in both lower limbs for over 5 months, along with excessive sweating on both palms and feet. A positive skin iodine-starch test was observed. Electromyography revealed extensive neurogenic damage and prolonged sympathetic skin response (SSR) latency in both lower limbs. Full exon gene sequencing showed a heterozygous mutation c.1574C>T (p.Pro525Leu) in the FUS gene. CONCLUSION: The pathogenesis of ALS remains unclear at present. This case underscores the presence of autonomic nervous symptoms in ALS associated with FUS mutation and highlights the importance of early diagnosis and timely treatment intervention to enhance patient prognosis.
