Abstract:Huntington disease (HD) is a neurodegenerative disease with autosomal dominant inheritance and is caused by abnormal amplification of CAG trinucleotide repeats in the Htt gene. Classical symptoms include dance-like symptoms and cognitive and mental disorders. Many fruitful studies have been conducted in recent years, and new diagnostic and therapeutic strategies are being developed. It is believed that in the future, more and more clinicians will become familiar with this disease and patients with this disease will obtain effective diagnosis and treatment.
