X-trisomy is a sex chromosome abnormality occurring in women, in which three X chromosomes are present, rather than the normal pair. More common than Turner's syndrome, where only one X chromosome is present, X-trisomy usually remains undetected because affected individuals appear normal, experience puberty, and are usually fertile.
