129S6.Cg-Gcktm2Mgn/Vu

View other collections this resource is shared to.

These mice, which contain an inactivating, K414E mutation within the Gck gene, provide a model for Maturity Onset Diabetes of the Young, or MODY-GK.

During the generation of this line, male chimeric mice derived by injecting correctly targeted TL1 mESCs into blastocysts from C57Bl/6 animals were mated directly with 129S6 female mice, thereby maintaining the mutation in an inbred state. 

Cryostocks of both 8-cell embryos and sperm from this line exist only at the VCMR.
