Figure 3From: Xq28 (MECP2) microdeletions are common in mutation-negative females with Rett syndrome and cause mild subtypes of the diseaseFISH demonstrating mosaic MECP2 deletion. (A) interphase FISH: two signals correspond to two MECP2 copies in a nucleus without deletion and a single signal is observed in a nucleus lacking one MECP2 copy; (B) percentages of abnormal cells detected by array CGH and FISH.Back to article page
