• Novel FLCN Mutations and mRNA Rescue in BHD

  2026-08-14

  A 2026 study identified the rare FLCN variants p.W376R and p.Q44* in two Chinese Birt-Hogg-Dubé families and combined genetic segregation with cellular functional testing. Exogenous FLCN mRNA restored protein expression and normalized mTORC1 signaling in HEK293T cells, providing an early proof of concept for mRNA-based replacement while remaining distant from clinical therapy.
