Pathogenic REST variant causing Jones syndrome and a review of the literature

Abstract

Jones syndrome is a rare dominantly inherited syndrome characterized by gingival fibromatosis and progressive sensorineural hearing loss becoming symptomatic in the second decade of life. Here, we report a father and his two daughters presenting with a typical Jones syndrome phenotype. Exome sequencing identified a repressor element 1-silencing transcription factor (REST) (NM_005612.5) c.2670_2673del p.(Glu891Profs*6) variant segregating with Jones syndrome in the family. We review the clinical data from all previously published patients with Jones syndrome and previously published patients with pathogenic REST variants associated with gingival fibromatosis or sensorineural hearing loss. This study suggests that pathogenic REST variants are the cause of Jones syndrome.
