Autosomal Dominant Dyskinesia Associated with the ADCY5 Gene
摘要
Autosomal dominant dyskinesia caused by heterozygous pathogenic variants of the adenylate cyclase-5 (ADCY5) gene is a rare neurodegenerative disease typically with early onset and hyperkinesia, often complex, as the dominant clinical features. Non-familial cases caused by de novo gene variants predominate. Caffeine, in the form of coffee, has become widely used in treatment. Three cases of the disease are described: a familial case of a nine-year-old boy and a 54-year-old mother, a non-familial case of a four-yearold girl with common ADCY5 variant p.Arg418Gln, and a non-familial case of an eight-year-old boy with known variant p.Arg726Trp. In the familial case, the mother’s disease was much milder than her son’s and did not require treatment; the son showed an effect of coffee.
