MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] DEF6, or IBP, is a guanine nucleotide exchange factor (GEF) for RAC (MIM 602048) and CDC42 (MIM 116952) that is highly expressed in B and T cells (Gupta et al., 2003 [PubMed 12923183]).[supplied by OMIM, Mar 2008]
PHENOTYPE: Homozygous mutants spontaneously develop systemic autoimmunity. Females primarily are affected, displaying hypergammaglobulinemia, accumulation of effector/memory T cells and IgG+ B cells, and production of autoantibodies [provided by MGI curators]
