CGG REPEAT LENGTH vs. AMYGDALAVOLUME. Partial correlation between CGG repeat number and corrected right amygdala volume in premutation carriers with low repeat numbers (empty symbols) and high repeat numbers (filled symbols) separated by scanner strength (1.5 T=squares, 3.0 T=triangles). When controlling for age, the low-repeat group (CGG≥55 and <85) showed a significant negative correlation between CGG repeat length and corrected right amygdala volume (dashed line, r=−0.56). In the high end fragile X premutation group (CGG≥85) no significant correlation was found between CGG repeat length and corrected amygdala volume (solid line). Similar patterns were found for when comparing corrected left amygdala volume to CGG repeat length (not shown)
