Research Abstract |
The pattern of serum Ig level were different between mother and daughter with same AID mutation (R190X). The immune phenotype of HIGM2 (R190X) might be affected by the environmental factors or the other genetic factors. In HIGM2 (R190X), specific antibody of IgM class was expressed for long time by IgM memory B cells, in which have done somatic hypermutation. In HIGM2 (R190X), some B cell could switched IgM to IgG. This switched B cell might not survive for long time and IgG antibody might become disappeared.
