Diagnostic issues in a family with late onset type 2 neurofibromatosis.

abstract：PURPOSE:To determine a gene locus for a family with a dominantly inherited vestibulocerebellar disorder characterised by early onset, but not congenital nystagmus. DESIGN:Observational and experimental study. METHODS:We carried out a phenotypic study of a unique four generation family with nystagmus. We performed gen...
