BXD24/TyJ

Stock number: 005243
Research areas: Neurobiology Research, Research Tools

Description

The BXD set of RI strains is used in the genetic analysis of numerous complex or potentially complex physiologic phenotypes. The BXD strains are derived from the C57BL/6J (Stock No. 000664) and DBA/2J (Stock No. 000671) progenitor strains.

Detailed description

The BXD RI strains are used to study the genetics of behavioral phenotypes including alcohol and drug addiction, stress, and locomotor activity. The BXD set of RI strains also are used in the genetic analysis of numerous complex or potentially complex physiologic phenotypes including differences in organ weight and bone mineral density.

The strain distribution pattern (SDP) for the BXD RI strains is available through the Mouse Genome Informatics Contributed Data Sets and Gene Network. Additional tools and information are presented through the Mouse Phenome Database Specialized Strain Panel Query Form, and Gene Network .

Please note: BXD24TyRww/J (032926) has been inbred an additional 16 generations.

Development

The BXD set of RI strains was developed in the laboratory of Benjamin Taylor and was transferred to The Jackson Laboratory from Dr. Taylor's research colony upon his retirement. Of 42 BXD RI strains originally derived from the C57BL/6J (Stock No. 000664) and DBA/2J (Stock No. 000671), a number have become extinct over the years. The other BXD RI strains now being distributed are listed under "Related Recombinant Inbred Strains."

In 2004, BXD24/TyJ developed a spontaneous mutation, rd16, and was renamed BXD24b/TyJ. This strain, formerly BXD24a, was cryo-recovered in 2004 from 1988 embryo stocks (F80) and does not exhibit retinal degeneration. In 2009, BXD24b was renamed BXD24/TyJ-Cep290^rd16/J (Stock No. 000031) to reflect the discovery of the genetic basis of the mutation. At the same time the "a" was dropped from this strain name.
