Summary Van der Woude syndrome (VWS) is an autosomal dominant developmental malformation presenting with bilateral lower lip pits related to cleft lip, cleft palate and other malformations. We performed a whole-genome copy number variations (CNVs) scan in an Indian family with members suffering from VWS using 2·6 million combined SNP and CNV markers. We found CNVs affecting IRF6, a known candidate gene for VWS, in all three cases, while none of the non-VWS members showed any CNVs in the IRF6 region. The duplications and deletions of the chromosomal critical region in 1q32-q41 confirm the involvement of CNVs in IRF6 in South Indian VWS patients. Molecular network analysis of these and other cleft lip/palate related module genes suggests that they are associated with cytokine-mediated signalling pathways and response to interferon-gamma mediated signalling pathways. This is a maiden study indicating the involvement of CNVs in IRF6 in causing VWS in the Indian population.
