Phenotype

In addition to hypopigmentation, lysosomes and platelets are functionally abnormal. Eye color for homozygous mice is red, then darkens to ruby; Wildtype and Heterozygous eye color is black

In mice, at least 16 HPS genes have been identified. They are involved with maturation of lysosomal-related organelles, including pigment cells, and most are components of specific protein complexes, BLOC-1 (pallid, cappuccino, muted loci), BLOC-2 (ruby eye and ruby eye-2 and cocoa), BLOC-3 and BLOC-4 (HPS1/pale ear and HPS4/light ear). HPS genes function in the biogenesis of lysosomes and lysosome-related cell-specific organelles such as melanosomes (found in pigment cells in skin, eye, ear, and meninges), platelet dense granules, and lung lamellar bodies. The major pathologic conditions associated with HPS are oculocutaneous albinism, prolonged bleeding, cellular accumulation of ceroid-like pigment, and pulmonary fibrosis.

Ruby2 is a member of the BLOC-2 complex and is the result of a spontaneous mutant that arose in a substrain of C57BL. An insertion of a 1.0 kb fragment of H2f2a that contains an 8 nt duplication at the 3' end was identified immediately upstream of codon 868 (exon 18).

Colony and Husbandry Information

Feed 9% fat breeder diet. Homozygous mice are gray with red eyes. Wildtype and Heterozygous mice are black and cannot be distinguished from each other on the basis of coat color. Mate as trios for greater probability of survival of young; may do better on second litter. If in danger of loss, mate to B6 and use the black heterozygous females with homozygous mutant males.

Colony Surveillance Program and Current Health Reports

Mice recovered from a cryo-archive will have health surveillance performed on recipient females. Health reports will be provided prior to shipment. If you require additional health status information, please email mmrrc@missouri.edu.

Coat color: Homozygous are gray; Wildtype and Heterozygous are black

Order Request Information

Limited quantities of breeder mice (recovered litter) are available from a cryoarchive; recovered litter usually available to ship in 3 to 4 months.

Distribution of this strain requires submission of the MMRRC Conditions of Use (COU). A link to the COU web form will be provided via email after an order has been placed; the form should be completed then or the email forwarded to your institutional official for completion.
Additional charges may apply for any special requests. Shipping costs are in addition to the basic distribution/resuscitation fees. Information on shipping costs and any additional charges will be provided by the supplying MMRRC facility.

1 The distribution fee covers the expense of resuscitating mice from the cryo-archive; you will receive the resulting litter. The litter will contain at minimum one mutant carrier; the actual number of animals and the gender and genotype ratios will vary. (Typically, multiple breeder pairs can be established from the recovered litter.) Prior to shipment, the MMRRC will provide information about the animals recovered. If you anticipate or find that you need to request specific genotypes, genders or quantities of mice in excess of what is likely from a resuscitated litter, you may discuss available options and pricing with the supplying MMRRC facility.

2 An aliquot is one straw or vial with sufficient sperm to recover at least one litter of mice, as per provided protocols, when performed at the MMRRC facility. The MMRRC makes no guarantee concerning the success of these procedures when performed outside the MMRRC facilities.

3 An aliquot contains a sufficient number of embryos (in one or more vials and based on the transfer success rate of the MMRRC facility) to transfer to at least two recipients. The MMRRC makes no guarantee concerning embryo transfer success experienced in the recipient investigator's laboratory. Neither gender nor genotype ratios are guaranteed.
