Figure 1.
Examples of electrophoresed products of repeat-primed polymerase chain reaction used to detect expansions in C9ORF72. Each panel was scaled to 800 fluorescent units on the y-axis and between 300–650 bp on the x-axis. (A) Data from a FTLD patient sample without an expansion and (B) data from a patient with FTLD with 2 and >60 repeats.
