There are also cases of brachycephaly associated with plagiocephaly. Norics were characterized by tall stature, brachycephaly, nasal convexity, long face and broad forehead. In brachycephaly both of the coronal sutures are prematurely fused. Brachycephaly in dogs is correlated to a retrotransposon induced missplicing the SMOC2 gene. Brachycephaly is the shape of a skull shorter than typical for its species.
