Venezuelan kindreds reveal that genetic and environmental factors modulate Huntington's disease age of onset

Nancy S. Wexler, +57 more
TL;DR: A model estimated the components of additive genetic, shared environment, and nonshared environment variances confirming that approximately 40% of the variance remaining in onset age is attributable to genes other than the HD gene and 60% is environmental.
Journal ArticleDOI

RORα-Mediated Purkinje Cell Development Determines Disease Severity in Adult SCA1 Mice

TL;DR: RORalpha and Tip60 have a role in SCA1 and suggest a mechanism by which compromising cerebellar development contributes to severity of neurodegeneration in an adult.
Journal ArticleDOI

SCA1-like disease in mice expressing wild-type ataxin-1 with a serine to aspartic acid replacement at residue 776.

TL;DR: It is shown that replacing Ser776 with a phosphomimicking Asp converted ATXN1 with a wild-type glutamine tract into a pathogenic protein, supporting a model where pathogenesis involves changes in regions of the protein in addition to the polyglutamine tract.
