    various types   abnormal protein/loss of function  
    Remark(s) . increased F-actin binding affinity of the mutants presents a biochemical mechanism that differentiates the autosomal dominant gain-of-function FLNB disorders from those that arise through the complete loss of FLNB protein (Sawyer 2010)
