Gene |
SMPD1 |
Chromosomal Location |
11p15.4-p15.1 |
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. |

Remarks |
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 GM27463 (iPSC). |
