description
Allele Type:    Targeted (Modified regulatory region)
Mutations:    Insertion, Intragenic deletion
 
Mutation detailsA neomycin resistance gene cassette replaced 1 kb including the MFCS4 (mammals-fish conserved sequence 4) enhancer of Shh located within intron 8 of Rnf32. This allele was created in ES cells that already carry the Rr114tm1.1Tshir allele (deletion of enhancer MRCS1). (J:320178)
