FBX07-R498X mutation: Phenotypic variability from chorea to early onset parkinsonism within a family

Abstract

Objective: FBXO7 mutations (PARK 15), first reported in 2008, are among the monogenic causes of early-onset parkinsonism. Classically, PARK 15 was suggested to correspond to previously described pallido-pyramidal syndrome. Here, we report clinical and genetic findings in a unique family of Kurdish origin with an FBXO7 mutation and presenting with diverse clinical phenotypes.
