Symbol:	Mthfrtm1Rzn
Name:	methylenetetrahydrofolate reductase; targeted mutation 1, Rima Rozen
MGI ID:	MGI:2385823
Synonyms:	Mthfr-
Gene:	Mthfr  Location: Chr4:148123534-148144008 bp, + strand  Genetic Position: Chr4, 78.67 cM
Alliance:	Mthfrtm1Rzn page

Germline Transmission:	Earliest citation of germline transmission: J:67779
Parent Cell Line:	R1 (ES Cell)
Strain of Origin:	(129X1/SvJ x 129S1/Sv)F1-Kitl+

Allele Type:    Targeted (Null/knockout) Mutation:    Insertion   Mutation details: Exon 3 was disrupted by the insertion of a neomycin selection cassette. Transcript was undetected by RT-PCR analysis of brain tissue obtained from homozygous mutant mice. Enzymatic activity assays showed a lack of activity in homozygous mutant mice and levels reduced to 60 to 70% of wild-type in heterozygotes. (J:67779)
