Mutation origin

• Strain of Origin: C57BL/6J

Mutation description

• Allele Type: Endonuclease-mediated (Humanized sequence)
• Mutation: Single point mutation
• Mutation details: Glycine codon 127 (GGC) in exon 4 was changed to valine (GTC) (c.380G>T:p.G127V) using an sgRNA (equivalent to TGCCACCTGACCCCCTAGGA) and an ssODN template with CRISPR/Cas9 technology. The mutation is the equivalent of the c.389G>T:p.G130V human mutation associated with Friedreich ataxia (FRDA). Transcription from this allele is normal, but translation is at about 5% of normal. (J:299300)
