Mutation
origin
Strain of Origin:  C57BL/6
Mutation
description
Allele Type:    Endonuclease-mediated (Humanized sequence)
Mutation:    Nucleotide substitutions
 
Mutation detailsCRISPR/Cas9 technology generated a GCGC to CTGG change resulting in an arginine to tryptophan substitution at amino acid 75 (p.R75W). This is a mutation that produces protein which is localized to the Golgi and was identified in patients with the X-linked form of Charcot-Marie-Tooth disease (CMTX1). (J:350504)
