FLNB regulates intracellular communication and signalling by cross-linking the protein actin to allow direct communication between the cell membrane and cytoskeletal network, to control and guide proper skeletal development.^[5]

Mutations in the FLNB gene are involved in several lethal bone dysplasias, including boomerang dysplasia and atelosteogenesis type I.^[6][7][8]
