| Induced Pluripotent Stem Cell |
The parental cell line was recovered, reprogrammed to an induced pluripotent stem cell line, 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. |

| Remarks |
Clinically affected; symptom onset at birth; diagnosed at 6 years of age; borderline microcephaly; intermittent exotropia; spastic diplegia; fetal pads present on fingers/toes; aplasia of the corpus callosum; pervasive developmental delay; moderate motor delay; stereotypic movements (biting hands); speech delay (receptive language better than expressive-uses some sign language); happy disposition; ADHD; drooling; constipation; normal EEG; genetic testing revealed subject is heterozygous for a nonsense mutation in the TCF4 gene (c.520C>T, p.Arg174X); medications: Amantadine, Tenex; Risperdal; therapies: speech therapy, special education; same subject as GM26037 (lymphoblast) and GM26038 (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 Sendai-CytoTune. |
