Abstract excerpt
Langerhans cell histiocytosis (LCH) represents a clonal proliferation of Langerhans cells. BRAF V600E mutations have been identified in approximately 50% of cases. To discover other genetic mechanisms underlying LCH pathogenesis, we studied 8 cases of LCH using a targeted next-generation sequencing platform. An E102_I103del mutation in MAP2K1 was identified in one BRAF wild-type case and confirmed by Sanger...
