Symbol:	Dntttm1Gfn
Name:	deoxynucleotidyltransferase, terminal; targeted mutation 1, Susan Gilfillan
MGI ID:	MGI:2177306
Synonyms:	TdT-
Gene:	Dntt  Location: Chr19:41017714-41047964 bp, + strand  Genetic Position: Chr19, 34.32 cM
Alliance:	Dntttm1Gfn page

Germline Transmission:	Earliest citation of germline transmission: J:14407
Parent Cell Line:	D3 (ES Cell)
Strain of Origin:	129S2/SvPas

Allele Type:    Targeted (Null/knockout) Mutation:    Insertion   Mutation details: A neomycin selection cassette was inserted into exon 4. RT-PCR and in situ hybridization analyses demonstrated that no detectable transcript was produced from this allele, and immunocytochemistry on thymocytes derived from homozygous mice confirmed that no detectable protein was expressed from this allele.
