The relationship between motor performance^a and the CAG repeats length in somatic tissues^b.

* Less repeats associated with longer time on the rod † More repeats associated with shorter time on the rod a. Time on the rotarod at 20rpm b. All the changes in CAG length were pooled for each tissue from birth to 40 weeks, the time frame of onset. c. The significance of the association between motor performance and somatic expansion was determined by linear regression. The coefficients were adjusted for Hdh(Q150) genotype, ogg1 genotype, age, and gender. P = probability. The relationship between motor performancea and the CAG repeats length in somatic tissuesb.
