Symbol: Efna2tm1Jgf
Name: ephrin A2; targeted mutation 1, John G Flanagan
MGI ID: MGI:2182943
Synonyms: A2-, ephrin-A2-
Gene: Efna2  Location: Chr10:80179482-80190010 bp, + strand  Genetic Position: Chr10, 39.72 cM
Germline Transmission:  Earliest citation of germline transmission: J:61499
Parent Cell Line:  TC1/TC-1 (ES Cell)
Strain of Origin:  129S6/SvEvTac
Allele Type:    Targeted (Null/knockout)
Mutation:    Insertion
Mutation detailsA neomycin selection cassette, containing stop codons in all three reading frames, was inserted after the sequence encoding amino acid 66. The insertion was upstream of a conserved cysteine residue motif. RT-PCR analysis of midbrain RNA showed an absence of transcript in homozygous mutant embryos. (J:61499)
