Figure 3From: AGG interruptions and maternal age affect FMR1 CGG repeat allele stability during transmissionMaternal age, total length, and number of AGG predict risk of full mutation expansion. The diagram shows the risk of expansion to a full mutation in a 20-, 30-, and 40-year-old premutation carrier mother predicted for 0 (black), 1 (red), and 2 or 3 (green) AGG interruptions and total length of CGG repeats.Back to article page
