Germline Transmission:  Earliest citation of germline transmission: J:94844
Parent Cell Line:  R1 (ES Cell)
Strain of Origin:  (129X1/SvJ x 129S1/Sv)F1-Kitl+
Allele Type:    Targeted (Null/knockout)
Mutations:    Insertion, Intragenic deletion
Mutation detailsA PGK-neo replaced a genomic fragment extending from the XbaI site at Chr5:88889874 (Build 37) in intron 4 to the EcoRI site at Chr5:88893057 in intron 6. Both exons 5 and 6 are thus deleted. Neither transcript nor protein was detected in mutant mice. (Additional information provided by authors.) (J:94844)
