Mutation description

• Allele Type: Targeted (Modified regulatory region)
• Mutation: Insertion
• Mutation details: A loxP-flanked neomycin resistance cassette has been inserted into the fourth of five HpaII sites within the LRRFIP1/GCF2 (leucine-rich repeat in FLII-interacting protein 1/GC-binding factor 2) repressor protein consensus binding sequence in the first differentially methylated region (DMR1) upstream of the imprinted insulin-like growth factor 2 (Igf2) gene. (J:178292)
• Inheritance: Other (see notes)

Notes

ES Cell LIne = CGR8.8, derived from 129P2/OlaHsd

This mutation affects the level of gene expression and expression dependent phenotypes in a parent of origin specific manner by interfering with the gene's imprinting.
