| Induced Pluripotent Stem Cell |
The cell line submitted to the Repository frozen was recovered and expanded. The expanded line was evaluated for viability surface antigen expression and alkaline phosphatase activity. Pluripotency was assessed via embryoid body (EB) formation and the PluriTest. Steady-state mRNA expression patterns of undifferentiated iPSCs and EBs were determined via real-time PCR. Characterization data are included in the Certificate of Analysis. |

| Identified Mutation |
(GAA)n EXPANSION; GAA triplet repeat expansions between 200 and 900 copies in the first intron of the frataxin gene occurred in 71 out of 74 FRDA patients studied by Campuzano et al. [Science 271: 1423-1427 (1996)]. In unaffected individuals the triplet expansion numbered between 7 and 20 units. |
