Although there is no specific treatment for FXTAS, FMR1-associated premature ovarian failure, or the psychiatric and musculoskeletal manifestations of Fragile X premutation, establishing the correct diagnosis might prevent unnecessary additional testing and procedures.
According to Paul Hagerman, "Fundamental research on neuronal function in both human and mouse cultured cells, as well as work in whole animals, will expand our knowledge of the processes that underlie both fragile X syndrome and FXTAS.
