Signaling through IL2Rγ is required for the differentiation and function of many hematopoietic cells. IL2Rγ is a common component of the cell surface receptors that bind and transduce signals from six distinct interleukins. The Il2rg tm1Wjl targeted mutation b is a complete null mutation in the gene encoding the interleukin 2 receptor gamma chain (IL2Rγ, homologous to IL2RG in humans).Due to the Prkdc scid mutation, however, the NSG strain shows high sensitivity to radiation, T-cell leakage, and increased incidence of thymic lymphoma formation as such, this strain cannot be used to predict clinical response to certain anticancer drugs, or for long-term transplantation studies. ![]() The phenotypic penetrance of Prkdc scid varies among inbred strain backgrounds, but the mutation is most effective at eliminating adaptive immunity on the NOD genetic background. Mice homozygous for the mutation have severely reduced numbers of mature T and B cells. Prkdc scid is a loss-of-function mutation in the mouse homologue of the human PRKDC gene, which encodes a protein that resolves DNA strand breaks that occur during V(D)J recombination in developing T and B lymphocytes.
