Germline Transmission:  Earliest citation of germline transmission: J:39092
Parent Cell Line:  AB2.1 (ES Cell)
Strain of Origin:  129S7/SvEvBrd-Hprtb-m2

Mutation detailsA 0.7kb genomic fragment containing exon 4 was replaced with a neomycin selection cassette. RT-PCR and RNAse protection assays demonstrated that a mutant transcript is produced from this allele that splices exon 3 to exon 5, which results in a frameshift mutation. Immunohistochemistry analysis revealed that no encoded protein was detectable in spleen sections from homozygous mice. (J:39092)
