ï»¿ Triple X syndrome is a chromosomal variation which is indicated by the presence of one extra X chromosome in each cell of a human female. Unlike most other chromosomal conditions, there is usually no noticeable difference to the naked eye between women with triple X syndrome and the rest of the female population.n most cases triple X syndrome is asymptomatic. This is because Lyonization (or X-inactivation) causes one of the two copies of the X chromosome in a normal female cell to de-activate. Usually this process also de-activates the extra X chromosome in superfemales.
