Germline Transmission:  Earliest citation of germline transmission: J:83911
Parent Cell Line:  Not Specified (ES Cell)
Strain of Origin:  129
Allele Type:    Targeted (Null/knockout)
Mutation:    Insertion
Mutation detailsA Lys256Glu mutation, such as is associated with familial focal and segmental glomerulosclerosis (FSGS) was introduced into exon 8. In addition, a loxP flanked neomycin-resistance cassette was inserted 400 base pairs 3' of exon 8. Contrary to expectations the resulting homozygous mice failed to express the mutated gene as was indicated by Northern and Western blots. (J:83911)
