title: Patterns of meiotic variability of the (CAG)n repeat in the Huntington disease gene.
abstract: We have collected 76 parent-offspring (CAG)n values in 60 French Huntington's disease (HD) pedigrees. The analysis of intergenerational alterations in CAG repeat length shows that there is a correlation between repeat instability and parental repeat length. Paternally inherited cases are characterized by a preferential trend towards an increase in range of repeat sizes in offspring of HD patients.
