Dysmorphic Syndromes

Syndromes of facial dysmorphism may present very variable phenotypes even when the underlying molecular basis is similar. Several well-known craniofacial abnormalities have been found to be alleles at the same locus.

Keywords: dysmorphism; craniofacial; development; holoprosencephaly; facial asymmetry; craniosynostosis
