[[http://www.uniprot.org/uniprot/GELS_HUMAN GELS_HUMAN]] Defects in GSN are the cause of amyloidosis type 5 (AMYL5) [MIM:[http://omim.org/entry/105120 105120]]; also known as familial amyloidosis Finnish type. AMYL5 is a hereditary generalized amyloidosis due to gelsolin amyloid deposition. It is typically characterized by cranial neuropathy and lattice corneal dystrophy. Most patients have modest involvement of internal organs, but severe systemic disease can develop in some individuals causing peripheral polyneuropathy, amyloid cardiomyopathy, and nephrotic syndrome leading to renal failure.<ref>PMID:2157434</ref> <ref>PMID:2153578</ref> <ref>PMID:2176481</ref> <ref>PMID:1338910</ref>

[[http://www.uniprot.org/uniprot/GELS_HUMAN GELS_HUMAN]] Calcium-regulated, actin-modulating protein that binds to the plus (or barbed) ends of actin monomers or filaments, preventing monomer exchange (end-blocking or capping). It can promote the assembly of monomers into filaments (nucleation) as well as sever filaments already formed. Plays a role in ciliogenesis.<ref>PMID:20393563</ref>  [[http://www.uniprot.org/uniprot/ACTS_CHICK ACTS_CHICK]] Actins are highly conserved proteins that are involved in various types of cell motility and are ubiquitously expressed in all eukaryotic cells.
