| 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. |

| Chromosomal Location |

| Allelic Variant 1 |
607608.0010; NIEMANN-PICK DISEASE, TYPE A |
| Identified Mutation |
LEU302PRO; Levran et al. (Blood 80: 2081-2087, 1992) reported a T-to-C transition at nucleotide 905, predicting a leucine-to-proline substitution at SMPD1 codon 302 in 8 of 34 (23.5%) Ashkenazi type A Niemann-Pick disease (257200) alleles studied. In contrast, it was not found in any of the SMPD1 alleles from non-Jewish type A patients or in alleles from type B patients or in 100 SMPD1 alleles from normal Ashkenazi Jewish persons. Three mutations, R496L (607608.0001), 1-BP DEL, PRO330FS (607608.0011), and this mutation, account for about 65% of the mutant SMPD1 alleles in Ashkenazi Jewish type A Niemann-Pick disease patients. |

Cell line ID: HT138C from parental fibro GM16195 - PMID 27484861 (Corrigendum PMID 34310862); Clinically affected; organomegaly; neurological involvement; deceased; Type A; acid sphingomyelinase enzyme levels <1% of controls; the donor subject is homozygous for a T-to-C transition at nucleotide 905 (CTT>CCT) of the SPMD1 gene, resulting in a leucine-to-proline substitution at codon 302 [LEU302PRO (L302P)]; same subject as GM16195 (parental 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. |
