Germline Transmission:  Earliest citation of germline transmission: J:89822
Parent Cell Line:  Not Specified (ES Cell)
Strain of Origin:  129X1/SvJ
Allele Type:    Targeted (Null/knockout)
Mutations:    Insertion, Intragenic deletion
Mutation detailsThe P1 promoter and exon 1 were replaced with a neo cassette via homologous recombination. This specifically deleted the Runx2-II isoform and not the Runx2-I isoform. Rt-PCR confirmed the absence of Runx2-II RNA and the presence of Runx2-I RNA. (J:89822, J:99696)
