Mutation origin

• Strain of Origin: C57BL/6J

Mutation description

• Allele Type: Endonuclease-mediated (Humanized sequence)
• Mutation: Nucleotide substitutions
• Mutation details: CRISPR/Cas9 technology generated a GTG to GGT change resulting in a valine to glycine substitution at amino acid 136 (p.V136G) in exon 2. This variant is associated with Alzheimers disease. In addition, a nonsense mutation (TCC to TCG) at codon 139 was introduced to prevent binding and recutting of the sequence. This is a loss-of-function mutation that attenuates ATP-release function. (J:368740)
