DEVELOPMENT MAPK Signaling 1: Development

Cardio-facio-cutaneous (CFC) syndrome is a rare disorder characterized by a distinctive facial appearance, skin abnormalities, heart defects, and growth delays. Rodriguez-Viciana et al. show that the disorder is caused by acquired mutations in genes encoding components of the mitogen-activated protein kinase (MAPK) signaling pathway. About 90% of the 23 patients studied carried missense mutations in the BRAF, MEK1, or MEK2 genes that functionally altered the corresponding proteins. This discovery highlights the critical role of the MAPK pathway in human development and provides a tool for molecular diagnosis of CFC syndrome.
