Mutation description

• Allele Type: Targeted (Humanized sequence, Inserted expressed sequence)
• Mutation: Insertion
• Mutation details: A fragment extending from 18 bp upstream of the polyglutamine stretch in exon 1 to 100 bp into intron 1 was replaced with human HD sequence obtained from a juvenile HD lymphoblastoid cell line. Though the initial construct was believed to contain 71 CAG repeats, sequence analysis identified an A to G point mutation in the 42nd CAG repeat, resulting in an arginine encoding triplet. Western blot analysis of heterozygous mice verified the expression of the mutant protein. (J:76018)
