Huntington's disease is an autosomal-dominant inherited neurodegenerative disease with a distinct phenotype. But the pathogenesis is very much unclear.

By mutation screening for CAG repeats in the Huntington's disease-associated candidate gene, IT15, using reverse transcription-polymerase chain reaction, T-A cloning, and sequencing, Dr. Mingxia Yu and coworkers from Zhongnan Hospital of Wuhan University in China provide a global analysis incorporating clinical symptoms, imaging examinations, and gene diagnosis, of Huntington's disease.
Their findings, published in the Neural Regeneration Research (Vol. 9, No. 4, 2014), suggest that clinical diagnosis of Huntington's disease requires a combination of clinical symptoms, radiological changes, and genetic diagnosis.
