Figure 5.—

Three deficiency regions with changes in repeat instability. The percentage of offspring exhibiting contractions, +1 expansions and greater than or equal to +2 expansions of the maternally inherited CAG₂₇₀ repeats. The deficiencies are grouped separately, comparing with the average of all crosses and the wild-type (WT) control for the same genetic background. Asterisks indicate percentages significantly different from the average of all samples (*P < 0.05, **P < 0.01, ***P < 0.001 (unpaired t-test, two tailed) compared to average of all crosses for that background). Error bars, SD.
