Mutation origin

• Strain of Origin: C57BL/6J

Mutation description

• Allele Type: Endonuclease-mediated (Humanized sequence)
• Mutation: Single point mutation
• Mutation details: CRISPR/Cas9 technology generated an A to G nucleotide change at position 1009 resulting in a methionine to valine substitution at amino acid 337 in exon 6. Analysis of mRNA levels and protein levels in the brain shows no difference in expression level from wild-type. Splicing of mRNAs regulated by TARDBP is deregulated in spinal cords, indicating a gain of splicing function. The M337V mutation is seen in patients with amyotrophic lateral sclerosis. (J:285477)
