Molecular and repeat-expansion properties of the mice measured in Figure 1

Dataset feature	Count	SEM
Number wt mice	57	—
Number exp-CGG mice	97	—
Largest repeat contraction	161	—
Largest repeat expansion	143	—
Avg repeat contraction	17	±5.0
Avg repeat expansion	31	±5.3
Avg exp-CGG-repeat length	143	±5.8
Avg exp-CGG Fmr1 mRNA level	3.2	±0.24
Avg exp-CGG FMRP level	0.62	±0.021
Avg exp-CGG translation	0.29	±0.023

Molecular measurements are all versus wt, the average of which was set to 1. exp, expanded; avg, average.
