WebFragile X syndrome takes its name from the appearance of the stained X chromosome under a microscope. There is a site near the end of this chromosome that does not stain, indicating its fragility. (Note: This methodology is no longer used for Fragile X testing). The gene in the fragile region is important in making a special protein needed by WebFXS is caused by FMR1 full mutations. Characteristics of Fragile X Tremor Ataxia Syndrome (FXTAS): Onset of progressive ataxia and intention tremor typically after the fourth decade of life. Females also have a 21 percent risk for primary ovarian insufficiency. FXTAS is caused by FMR1 premutations. Incidence of FXS: 1 in 4,000 Caucasian males ...
