| Induced Pluripotent Stem Cell |
The frozen cell line submitted to the Repository 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. Steady-state mRNA expression patterns of undifferentiated iPSC and EBs were determined via real-time PCR. Characterization data are included in the Certificate of Analysis. |

606829.0001; FRIEDREICH ATAXIA |
| 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. |

| Remarks |
iPS cell line made from GM03816; clinically affected; spinal-cerebral degeneration with myocardiopathy; a brother (GM04078/GM04079)is similarly affected; homozygous for the GAA expansion in the frataxin gene with alleles of approximately 330 and 380 repeats. Researchers purchasing hiPSCs from the NIGMS Repository are responsible for any limited use label licenses (LULLs) applicable to the cell line purchased. The applicable LULL to this line is iPS Academia Japan, Inc.. |
