Electropherogram results for samples with unusually large CAG expansions. (A) Electable 16. showing alleles of 17/81 CAG repeats and a continuous stuttering after the first prominent peak. (B,C) show sample MGM16-1035 and sample MGM18-1332, respectively, with the presence of a pile-up peak at the end of the run representing the high CAG expansion of 200 repeats (zoom of pile-up in B,C).
