Mutation description

• Allele Type: Targeted (Constitutively active, Humanized sequence)
• Mutation: Single point mutation
• Mutation details: An asparagine to lysine substitution at amino acid 534 (p.N534K) was introduced in exon 12. A loxP-flanked neomycin/STOP cassette that was inserted upstream of exon 11 was removed via flp-mediated recombination. This corresponds to the p.N540K gain-of-function mutation identified in patients with hypochondroplasia. (J:338859)
