• MGI ID: MGI:6197715
• Synonyms: R47H ki, Trem2(R47H)
• Gene: Trem2 Location: Chr17:48653429-48659304 bp, + strand Genetic Position: Chr17, 23.99 cM, cytoband C

Mutation origin

• Strain of Origin: (C57B/6J x DBA/2J)F1 x FVB/N

Mutation description

• Allele Type: Endonuclease-mediated (Humanized sequence)
• Mutation: Nucleotide substitutions
• Mutation details: The allele was generated by injecting cas9 nuclease and a single guide RNA designed to introduce an arginine to histidine (R27H) point mutation with three silent mutations GA>TC to create a restriction enzyme site for genotyping and G>A to block the protospacer-adjacent motif to allow higher editing efficiency. Western blot of microglia and bone marrow derived macrophages confirms a reduction in protein levels. (J:264639)
