The interferon regulatory factor 6 gene (IRF6) has been identified as the major Van der Woude (VWS) syndrome and popliteal pterygium (PPS) syndrome gene with mutations in the majority of the kindreds. In a recently published article in the European Journal of Human Genetics (Vol.13, pp. 1261–1267), the authors have studied altogether 17 kindreds from Sweden, Finland, Norway, Thailand and Singapore, and report here 10 mutations, six of them previously unseen. Their findings demonstrate that several distinct mutations occur in the Swedish population, and confirm the general notion of a broad spectrum of IRF6 mutations underlying the VWS/PPS phenotypes.
