Genetic Alterations
ENU-induced A to G transition at base pair 34,708,793 (v38) on chromosome 11, or base pair 75,113 in the GenBank genomic region NC_000077 for the Dock2 gene. The mutation corresponds to residue 1,040 in the NM_033374 mRNA sequence within exon 10 of 52 total exons. The mutation results in an arginine (R) to glycine (G) substitution at position 320 (R320G) in the DOCK2 (dedicator of cytokinesis 2) protein.

Strain Description

Phenotype

Homozygous: Mice showed a decrease in the CD4+ to CD8+ T cell ratio caused by a diminished frequency of CD4+ T cells and a reduced frequency of CD4+ T cells in CD3+ T cells coupled with an increased frequency of CD8+ T cells in CD3+ T cells, all in the peripheral blood. Some mice also exhibited an increase frequency of B1b cells in B1 cells in the peripheral blood.

Heterozygous: No abnormal phenotype detected.

Mammalian Phenotype Terms

Strain Development
Original mutant was a C57BL/6J G3 ENU-induced mutant; all subsequent crosses to maintain strain were on C57BL/6J background only.
Suggested Control Mice
Wild-type littermates or C57BL/6J mice
