Mutations in the GSN gene have been linked to familial amyloidosis of Finnish type (FAF) or gelsolin amyloidosis [MIM#105120], a rare, autosomal dominant hereditary amyloid polyneuropathy, mainly characterized by progressive cranial neuropathies, corneal lattice dystrophy, and sensory neuropathy [25]. This evidence concerns the gene GSN and Familial amyloidosis, Finnish type.
