BRAF postzygotic activating mutations have been found in 50% of cases of syringocystadenoma papilliferum (SCAP) and in phacomatosis pigmentokeratotica (PPK) , also possibly caused by HRAS mutations. BRAF is a RAS-activating serine/threonine kinase of the MAP kinase pathway, resulting in cell growth and proliferation. BRAF mutations, particularly p.(Val600Glu), are frequently identified in melanoma and other human cancers . We report clinical presentations of three patients with postzygotic BRAF mutations in affected skin, identified by next generation sequencing (NGS).
