• MGI ID: MGI:5635256
• Synonyms: ssTnT-KO, Tnnt1-exon 11-13 deletion
• Gene: Tnnt1 Location: Chr7:4507568-4518974 bp, - strand Genetic Position: Chr7, 2.6 cM
• Alliance: Tnnt1^tm1.2Jin page

Mutation origin

• Germline Transmission: Earliest citation of germline transmission: J:219907
• Parent Cell Line: HM-1 (ES Cell)
• Strain of Origin: 129P2/OlaHsd-Hprt1^b-m3

Mutation description

• Allele Type: Targeted (Null/knockout)
• Mutations: Insertion, Intragenic deletion
• Mutation details: LoxP sites were inserted into intron 10 and intron 13. Cre-mediated recombination removed exons 11 through 13. The predicted truncated product mimicks the protein involved in Amish nemaline myopathy. A FRT-flanked neomycin resistance cassette was inserted into intron 10. Western blot analysis confirmed the absence of protein expression in the soleus muscle. (J:219907)
