Many physicians are unaware of the many phenotypes associated with the fragile X
premutation, an expansion in the 5′ untranslated region of the fragile X mental retardation …

The premutation of the fragile X messenger ribonucleoprotein 1 (FMR1) gene is
characterized by an expansion of the CGG trinucleotide repeats (55 to 200 CGGs) in the …

The fragile X-associated tremor/ataxia syndrome (FXTAS) is a neurodegenerative disorder
seen in older premutation (55–200 CGG repeats) carriers of FMR1. The premutation has …

Fragile X–associated tremor/ataxia syndrome (FXTAS) is a late‐onset neurodegenerative
disorder that affects some but not all carriers of small, noncoding CGG‐repeat expansions …

Carriers of the fragile X premutation (FPM) have CGG trinucleotide repeat expansions of
between 55 and 200 in the 5′-UTR of FMR1, compared to a CGG repeat length of between …

Fragile X-associated tremor/ataxia syndrome (FXTAS) is a late-onset neurodegenerative
disorder affecting approximately 45% of male and 16% of female carriers of the FMR1 …

Fragile X-associated tremor/ataxia syndrome (FXTAS) is a late-onset neurodegenerative
disorder typically affecting male premutation carriers with 55–200 CGG trinucleotide repeat …

Background Carriers of the FMR1 premutation are at increased risk of developing a late-
onset progressive neurodegenerative disease, fragile X-associated tremor/ataxia syndrome …

Fragile X syndrome (FXS) is the most common single gene cause of intellectual disability
and it is characterized by a CGG expansion of more than 200 repeats in the FMR1 gene …

Background: Fragile X‐associated tremor/ataxia syndrome is an adult‐onset disorder
associated with premutation alleles of the FMR1 gene. This disorder is characterized by …
