| 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. |

| Identified Mutation |
1-BP DEL, PRO330FS; Levran et al. (Blood 80: 2081-2087, 1992) described a new mutation that causes type A Niemann-Pick disease (257200) in Ashkenazi Jewish patients. Deletion of a single cytosine in codon 330 of the SMPD1 cDNA (which normally encodes a proline residue) caused a frameshift that led to the formation of a premature stop (TGA) at codon 382. Three mutations, R496L (607608.0001), L302P (607608.0010), and this mutation, account for about 65% of the mutant SMPD1 alleles in Ashkenazi Jewish type A Niemann-Pick disease patients. The single base deletion causing the pro330FS mutation was in a region of the gene where 9 of the 10 residues were cytosines. |
| Remarks |
Cell line ID: HT139B from parental fibro GM13205 - PMID 27484861 (Corrigendum PMID 34310862); Ashkenazi; developmental delay; hypotonia; does not show marked hepatosplenomegaly; no detectable sphingomyelinase activity in WBC and fibroblasts; donor subject has one allele with a deletion of a single cytosine in exon 2 at codon 330 of the SMPD1 gene [990delC] resulting in a frameshift leading to the formation of a premature stop (TGA) at codon 382 [P330fsX382]; same subject as GM13205 (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. |
