Genotype a/a B/B C/C  
Strain development Developed by Tasuku Honjo, Graduate School of Medicine, Kyoto University. The construct was electoroporated into TT2 ES cells derived from (C57BL/6 x CBA)F1. The mutant mice were backcrossed to C57BL/6N.  
Strain description AID (Aicda, activation-induced cytidine deaminase) knockout mice. Exon 2 and part of exon 3 were replaced with a neomycin resistance cassette. Aid, Activation-Induced cytidine Deaminase is a molecule which specifically expressed in B lymphocytes after antigen stimulation. AID deficiency caused a complete defect in class switching and showed a hyper-IgM phenotype with enlarged germinal centers containing strongly activated B cells before or after immunization. Accumulation of IgM positive B cell is remarkable in the gut lamina propria. Furthermore, it is suggested that a mutation of the Aid gene was a cause of the hereditary immune deficiency disorder, type-2 hyper-IgM syndrome (HIGM2) in human. As well as class switch recombination, it was also indicated that somatic hypermutation of an immunoglobulin variable region gene and gene conversion do not occur at all in the Aid deficiency mice. Aid gene is a molecule serving as a central role in antibody gene variety acquisition mechanism of B cell.  
Colony maintenance Homozygote x Homozygote. Homozygous mutant mice are viable and fertile.
