Background: Premutation alleles of the FMR1 X-linked gene containing CGG repeat expansions ranging from 55 to 200 are associated with diverse late-onset neurological involvements, including most severe disorder termed Fragile X-associated Tremor/Ataxia Syndrome (FXTAS). It is intriguing that at least one-third of male, and a much lower than predicted from the X-linkage proportion of female carriers are free of this syndrome. This suggests the existence of secondary genetic factors modifying the risk of neurological involvements in these carriers.

We examined prevalence of age-related hearing loss (ARHL) in healthy, community-dwelling older adults, and determined whether sociodemographic, lifestyle or health factors associate with hearing thresholds. Audiometry assessment was investigated with self-reports of hearing loss and hearing handicap.
