Mutation detailsA point mutation was introduced into BAC RP23-311P1 that results in the R504X mutation in the encoded protein. This point mutation corresponds to the human R493X mutation causally linked to PGRN-linked FTLD. This BAC was used to create a targeting vector, and homologous recombination in ES cells and production of chimeric mice transmitted the mutation into the mouse germline. A neomycin selection cassette was removed by Cre-mediated recombination in mice. Western blot analysis shows that level of full-length protein is reduced in the cerebral cortex (J:259943)
