Genetic information | The IgH 3’ regulatory region (3’RR) controls class switch recombination (CSR) and somatic hypermutation (SHM) in B cells. The mouse 3’RR contains four enhancer elements with hs1,2 flanked by inverted repeated sequences and the center of a 25-kb palindrome bounded by two hs3 enhancer inverted copies (hs3a and hs3b); hs4 lies downstream of the palindrome. We generated and analysed mice without the left part of the 3'RR (hs3a-IRIS-hs1,2): Delta2-3'RR-deficient mice |
Phenotypic information | Homozygous:Decrease of somatic hypermutation rate in VH gene. Decrease of class switch recombination. Decrease in circulating Ig levels. Decrease of germinal transcription of IgH genes.Heterozygous:--- |
