Abstract: Interferon Regulatory Factor 6 (IRF-6) and p63 are two vital transcription factors implicated in normal
craniofacial development. In this report, we present a family with Van Der Woude Syndrome (VWS) with
a mutation in exon 9 of IRF-6 gene and a phenotypically overlapping case of Rapp-Hodgkin Syndrome
(RHS) resulting from a mutation in the p63 gene. Members from both families presented with congenital
lip pits and cleft lip/palate. The RHS case had additional ectodermal features that underscore the upstream
nature of p63 in the complex p63-IRF-6 interactive pathway.Keywords: Lip pits, p63-related disorders, ectodermal dysplasia, IRF-6
