Figure 2

C9ORF72 repeat-primed PCR assay in clinical AD patients. PCR products of C9ORF72 repeat-primed PCR reactions separated on an ABI3730 DNA Analyzer and visualized by GENEMAPPER software. Electropherograms are zoomed to 4,000 relative fluorescence units to show stutter amplification. The two clinical AD patients with expanded repeats (7391 and 9979) and one non-carrier (15077) are shown. Note the strong amplification in patient 7391 around ~470bp, suggesting a large proportion of cells carrying approximately 60 GGGGCC repeats, in addition to a smaller population of cells carrying longer repeat expansions.
