FLNA (Filamin-A) variants and mutations

FLNA (also known as Filamin-A) is a human protein-coding gene encoding a filamin-A protein. It crosslinks actin and connects the cytoskeleton to membrane receptors and signaling proteins during cell migration and tissue morphogenesis. Pathogenic variants cause a broad spectrum including periventricular nodular heterotopia and several skeletal or connective-tissue disorders. This analysis covers 2,953 FLNA variants and mutations. Of these, 69% have computational variant effect predictions. Disease context includes Melnick-Needles syndrome, heterotopia, periventricular, X-linked dominant, and otopalatodigital syndrome type 2. Example FLNA variants include S2C, S2N, and S3G.
