FRAGILE X TREMOR/ATAXIA SYNDROME
Scope Statement

Caused by 55-200 expanded trinucleotide repeats in the FMR1 gene (309550) referred to as a 'premutation' [MISCELLANEOUS]

Males are more commonly affected than females [MISCELLANEOUS]

Onset in fifties or sixties [MISCELLANEOUS]

Caused by trinucleotide repeat expansion (CGG)n in the fragile X messenger ribonucleoprotein gene (FMR1, 309550.0004) [MOLECULAR BASIS]

Most patients have a family history of fragile X syndrome [MISCELLANEOUS]

Full mutations with expanded trinucleotide repeats greater than 200 result in fragile X mental retardation syndrome (300624) [MISCELLANEOUS]
