| 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. |

15q23-q24 |
| Allelic Variant 1 |
606869.0001; TAY-SACHS DISEASE |
| Identified Mutation |
c.1274_1277dupTATC; Myerowitz and Costigan [J Biol Chem 263: 18587 (1988)] demonstrated that the most frequent DNA lesion in Tay-Sachs disease of Ashkenazi Jews is a 4-bp insertion in exon 11. This mutation introduces a premature termination signal in exon 11, resulting in a deficiency of mRNA. This is the most frequent defect underlying Tay-Sachs disease in the Ashkenazi Jewish population. This mutation is alternatively designated 1277TATC; see 272800.0054. |

| Allelic Variant 2 |
606869.0008; GM2-GANGLIOSIDOSIS, ADULT ONSET |
| Identified Mutation |
GLY269SER; In 8 Ashkenazi adult GM2 gangliosidosis patients from 5 different families, Navon and Proia [Science 243: 1471 (1989)] identified a G-to-A substitution at the 3-prime end of exon 7, resulting in the substitution of serine for glycine at position 269. |
| Remarks |
Adult onset; deficient hexosaminidase A activity in plasma and fibroblasts; donor subject is a compound heterozygote: one allele has a 4 bp insertion at nucleotide 1278 in exon 11 of the HEXA gene (c.1278insTATC); the second allele has a G>A substitution at nucleotide 805 in exon 7 (c.805G>A) resulting in a substitution of serine for glycine at codon 269 [Gly269Ser (G269S)]; 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. |
