Mutation origin

• Strain of Origin: Not Specified

Mutation description

• Allele Type: Other
• Mutation: Intragenic deletion
• Mutation details: This mutation was identified during an irradiation experiment, but it is not known whether it was induced in the treated male or spontaneously arose in an untreated mate. RT-PCR analysis identified a 3 nucleotide deletion in the transcript that results in a loss of one of four conserved arginine residues in the basic domain of the encoded protein. This mutation is predicted to affect the ability of the protein to bind DNA. (J:13562)
• Inheritance: Semidominant

Notes

This mutation produces an osteopetrosis that resembles human osteopetrosis more than that produced by Ctsf^op. Mitf^Mi mutant mice have normal levels of M-CSF and its receptor. Osteoplasts are produced, but are unable to function normally in bone resorption (J:22788).

Combination heterozygotes of Mitf^Mi-wh/Mitf^Mi show some interallelic complementation in that the heterozygote of the two alleles is more nearly normal than either homozygote (J:12967). Mitf^Mi-Or/Mitf^Mi mice resemble homozygous Mitf^Mi-Or (J:15060).
