This very rare cluster of anomalies has been well reported before. However only until recently it is recognized as a syndrome belonging to frontonasal dysplasia spectrum. The ten cases confirm a distinct clinical entity and help to define the phenotype more precisely than previously. Up to now etiology remains unknown although we conjecture that it is due to a mutation in TGIF gene.
