Mutation description

• Allele Type: Targeted (Humanized sequence)
• Mutations: Insertion, Nucleotide substitutions
• Mutation details: A loxP-flanked Polr3a cDNA encoding wild-type exons 15 to 31 and a downstream heterologous polyadenylation signal, followed by intronic sequences and mutant exon 15 encoding the leukodystrophy mutations W671R and G672E were inserted downstream of exon 14. Cre-mediated recombination removed the floxed wild-type exons 15-31, leaving the mutant exon 15. (J:311745)
