| 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. |

| Allelic Variant 1 |
164874.0007; RETT SYNDROME, CONGENITAL VARIANT |
| Identified Mutation |
c.460dupG (p.Glu154Glyfs*301); In 2 unrelated patients with the congenital variant of Rett syndrome (613454), Kortum et al. (2011) identified a heterozygous de novo 1-bp duplication (460dupG), resulting in a duplication of guanine after 7 subsequent guanine nucleotides in the FOXG1 gene. The recurrence of this mutation suggested that this guanine stretch is prone to replication errors, thus representing a mutation hotspot. |
| Remarks |
Clinically affected; normal pregnancy and birth; delay apparent by 12 weeks (not smiling until 20 weeks, poor head control, but was thriving); infrequent focal (left-sided) seizures; examined at 2y 11m: able to pick up food; MRI showed complete agenesis of corpus callosum; dystonia (treated with L-DOPA); mutation in FOXG1 gene: c.460dupG (p.E154GfsX301); same subject as GM27613 (fibroblast). 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.. |
