| molecularNote | A hypomorphic allele was generated by the deletion of the proximal epiblast enhancer (PEE), a 2 kb element located about 10 kb upstream of the first exon. The PEE element was initially replaced with a floxed PGK-hygro cassette that was subsequently removed in vitro, leaving a single loxP in its place. |
