Targeted Allele Detail
Symbol: H19tm1Masu
Name: H19, imprinted maternally expressed transcript; targeted mutation 1, M Azim Surani
MGI ID: MGI:1860836
Synonyms: H19SilK
Gene: H19  Location: Chr7:142575529-142578143 bp, - strand  Genetic Position: Chr7, 87.97 cM
Germline Transmission:  Earliest citation of germline transmission: J:63213
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 loxP-flanked neomycin resistance cassette replaced 1.2kb region of the promoter, corresponding to a cis-acting silencer element. This cassette was then excised in ES cells by cre-mediated recombination, resulting in the deletion of the silencer element. (J:63213)
Inheritance:    Dominant
