Mice homozygous for the recessive NIH allele of the Niemann Pick type C1 gene (Npc1m1N) show a dual deficiency of sphingomyelinase and glucocerebrosidase activity. The overall phenotype resembles the sphingomyelinosis condition seen in mice homozygous for the sphingomyelinosis allele (Npc1spm, Stock No. 002760). Sphingomyelinosis closely resembles that of human Niemann-Pick Type C disease patients.Read More +
Mice homozygous for the recessive NIH allele of the Niemann Pick type C1 gene (Npc1m1N) show a dual deficiency of sphingomyelinase and glucocerebrosidase activity. The overall phenotype resembles the sphingomyelinosis condition seen in mice homozygous for the sphingomyelinosis allele (Npc1spm, Stock No. 002760). Sphingomyelinosis mutant mice begin to lose weight and to show tremor and ataxic gait at about 7 weeks of age. Weight loss continues and tremor and ataxia become more severe until death at about 12 to 14 weeks of age. The liver and spleen are also enlarged and Purkinje cells in the cerebellum are severely depleted. Sphingomyelin and free cholesterol are markedly elevated in liver and spleen but not in brain. Sphingomyelinosis closely resembles that of human Niemann-Pick Type C disease patients.
The mutant allele consists of 824 bp of MaLR retroposon-like DNA which replaced 703 bp of wild-type genomic sequence spanning 44 bp of an exon and 659 bp of the downstream intron. A truncated gene product (mRNA) is detected by Northern blot analysis of liver and brain tissue from homozygous mice. No protein is detected by Western blot analysis of liver from homozygotes.
This mutation arose on the BALB/cNctr inbred background at the National Center for Toxicology Research (Jefferson, Arkansas) in 1975. The mutant allele consists of 824 bp of MaLR retroposon-like DNA which replaced 703 bp of wild-type genomic sequence. The mice were transferred to The Jackson Laboratory in 1982 from Dr. William Pavan (NIH).

|Strain of Origin||BALB/c|
|Molecular Note||824 bp of MaLR retroposon-like DNA replaced 703 bp of wild-type genomic sequence spanning 44 bp of an exon and 659 bp of the downstream intron. The insertion results in premature truncation of the protein deleting 11 out of 13 transmembrane domains. Northern blot analysis revealed marked decrease in gene expression in liver and brain from homozygous mutant animals.|
When maintaining a live colony, heterozygous mice may be bred to wildtype siblings. Homozygotes die at about 12 to 14 weeks of age.
When using the npcnih mouse strain in a publication, please cite the originating article(s) and include JAX stock #003092 in your Materials and Methods section.

The average number of mice provided from recovery of our cryopreserved strains is 10. The total number of animals provided,
their gender and genotype will vary. We will fulfill your order by providing at least two pair of mice, at least one animal of
each pair carrying the mutation of interest. Please inquire if larger numbers of animals with specific genotype and genders
are needed. Animals typically ship between 10 and 14 weeks from the date of your order. If a second cryorecovery is needed in
order to provide the minimum number of animals, animals will ship within 25 weeks.
The genotypes of animals provided may not reflect the mating scheme utilized by The Jackson Laboratory prior to cryopreservation, or that discussed in the strain description. Please inquire about possible genotypes which will be recovered for this specific strain. The Jackson Laboratory cannot guarantee the reproductive success of mice shipped to your facility. If the mice are lost after the first three days (post-arrival) or do not produce progeny at your facility, a new order and fee will be necessary.
Cryorecovery to establish a Dedicated Supply for greater quantities of mice. Mice recovered can be used to establish a dedicated colony to contractually supply you mice according to your requirements. Price by quotation.
