607608.0011; NIEMANN-PICK DISEASE, TYPE A |
| 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 |
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 GM27464 (iPSC).
