Study estimates how common carriers of polyglutamine disease-associated gene variants are in general population

Bottom Line: Huntington disease is one of nine rare hereditary neurodegenerative diseases known as polyglutamine diseases. This observational study estimated how common carriers with intermediate and pathological ranges of polyglutamine disease-associated gene variants were among the general population using data from five European studies that included DNA samples for more than 14,000 participants without a known polyglutamine disease diagnosis.
