Strain name: B6.129P2-Cited1tm1Dunw/Apb
Strain designation name: B6.129P2-Cited1tm1Dunw/Apb
Strain Types Mutant strain
Genetic Details Targeted knockout
ES Cell-Line Used E14.2
Mode of Inheritance X-linked
1.  Affected Gene Name: Cbp/p300-interacting transactivator with Glu/Asp-rich carboxy-terminal domian 1  
Chromosome X
Affected Gene Symbol Cited1
Protein expression of altered gene: Nil
Genetic alteration of gene: A loxP site was inserted 51bp upstream from the ATG and Cre/lox recombination used to replace the entire coding region with a GFP-PGKneo cassette.
Location on chromosome (bp): 96848743-96853525 bp, - strand (From Ensembl annotation of NCBI Build 34)

Synonyms Msg1, ER154
Allele Name Cited1 targeted mutation 1, Sally L Dunwoodie
Allele Symbol Cited1tm1Dunw
MGI Allele Accession ID MGI:3028946
Mutant Construction Technique CRE recombinase-loxP technology
Phenotype Homozygous State Results in impaired embryonic growth and survival due to defects in trophoblast and placental development.
Phenotype Heterozygous State Male hemizygotes have the same phenotype as the female homozygotes. Female heterzygotes have a variable phenotype depending on which parent the Cited1tm1Dunw allele is inherited from. Heterozygous females with paternally inherited Cited1tm1Dunw have no placental phenotype, whereas heterozygous females with maternally inherited Cited1tm1Dunw have the same placental phenotype as homozygotes
