Phenotype
Phenotype Information
- No similarity to the expected human disease phenotype was found. One or more human genes are associated with this human disease. The mouse genotype may involve mutations to orthologs of one or more of these genes, but the phenotype did not resemble the disease.
Huntington Disease; HD
assigned by genotype
Htttm2Mem/Htttm2Mem
involves: 129S1/Sv * 129X1/SvJ * CD-1
- nervous system phenotype
- *normal* nervous system phenotype
- unlike other Hdh alleles that are models for Huntington Disease, homozygotes show no change in striatal mitochondrial sensitivity to calcium in the brain, thus displaying normal striatal and cortical calcium sensitivity (MGI Ref ID J:99425)

| Molecular Note | This allele carries 18 CAG repeat units, with 20 glutamines, in the first exon of the endogenous gene, modeling the number of CAG repeats found in the human Hdh. It is a derivative of Hdhtm6Mem in which the neo cassette has been removed via cre-mediated recombination. [MGI Ref ID J:52440] | ||

Progeny testing is not required.
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 11 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. IMPORTANT NOTE: 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. For more information on Dedicated Supply, please contact JAX® Services, Tel: 1-800-422-6423 (from U.S.A., Canada or Puerto Rico only) or 1-207-288-5845 (from any location).

The Jackson Laboratory's Genotype Promise
The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project.Ordering Information
