Germline Transmission:  Earliest citation of germline transmission: J:136145
Parent Cell Line:  R1 (ES Cell)
Strain of Origin:  (129X1/SvJ x 129S1/Sv)F1-Kitl+
Allele Type:    Targeted (Conditional ready, Hypomorph)
Mutation:    Insertion
Mutation detailsA loxP site was inserted upstream of exon 2 and an frt-flanked neo cassette with a 3' loxP site was inserted downstream of exon 2. Aberrant splicing creates a hypomorphic allele with reduced expression levels. (J:136145)
