Figure 2From: AGG interruptions and maternal age affect FMR1 CGG repeat allele stability during transmissionDistribution of premutation allele total length. A histogram of the number of transmissions observed for each total CGG repeat length, grouped by 0 (black), 1 (red), and 2 or 3 (green) AGG interruptions. Transmissions that resulted in a premutation are partially shaded, and transmissions that expanded to a full mutation are shown as solid bars.Back to article page
