Genetic information | Targeting construct is derived from 129 DNA. For the original targeting construct, a loxP site was inserted upstream of exon 2, which contains the entire open reading frame, and an frt-flanked neo cassette with a 3' loxP site followed by a lacZ cassette was inserted downstream of exon 2. Germ line, flp-mediated recombination was used to remove the neo cassette leaving exon 2 flanked by 2 loxP sites and followed by the lacZ expression cassette. The allele was designed such that, after successful cre-mediated recombination, the lacZ expression cassette comes under the control of the endogenous Cited2 promoter. |
Phenotypic information | cre-mediated recombination throughout the entire epiblast of early embryos recapitulates the complete loss of function phenotype of Cited2, which include cardiac malformations, adrenal agenesis, fusion of cranial ganglia, abnormal cardiac neural crest migration, exencephaly and left-right patterning defects. |
Breeding history | The line is maintained by backcrossing to C57BL/6J. It has been backcrossed 10+ generations and SNP genotyped. Currently estimated to be >99.8% C57BL/6J. |
