Targeted Allele Detail
Symbol: Trhtm1Mmt
Name: thyrotropin releasing hormone; targeted mutation 1, Makoto M Taketo
MGI ID: MGI:3620126
Synonyms: TRH KO
Gene: Trh  Location: Chr6:92242061-92244650 bp, - strand  Genetic Position: Chr6, 41.03 cM
Germline Transmission:  Earliest citation of germline transmission: J:43657
Parent Cell Line:  TT2 (ES Cell)
Strain of Origin:  (C57BL/6NCrlj x CBA/JNCrlj)F1
Allele Type:    Targeted (Null/knockout)
Mutations:    Insertion, Intragenic deletion
Mutation detailsA neomycin selection cassette replaced sequences containing codons 70-211. Northern blot analysis indicated that no detectable transcript was expressed from this allele in hypothalamus, and radioimmunoassy experiments confirmed the absence of encoded protein from homozygous mice.

Mice homozygous for a targeted disruption of Trh are viable, fertile, and develop normally. They exhibit, however, a tertiary hypothyroidism with elevated TSH levels, suggesting a direct effect of TRH on pituitary thyrotrophs. Impaired insulin secretion and hyperglycemia also occur in these mice (J:43657).
