Correction: A mouse model of Greig cephalapolysyndactyly syndrome: the extra-toes^J mutation contains an intragenic deletion of the Gli3 gene

Nature Genet. 3, 241– 246 (1993).

Originally, we reported that the 3′ end of Gli3 is not deleted in the Xt^J allele (Fig. 4). U. Rüther brought to our attention that the Xt^J allele indeed contains a deletion including the 3′ UTR of Gli3. Subsequently, we repeated the experiments and found that the data described in Fig. 4 using probe d was due to probe d containing sequences other than Gli3. These findings indicate that the deletion in the Xt^J allele might not be intragenic; however, it does not affect our main conclusion that Xt^J is a mouse model of GCPS. We regret this error.
