Due to the lyonization, inactivation and formation of a Barr body in all female cells, only one X chromosome is active at any time in a female cell. Thus, triple X syndrome most often causes no unusual physical features or medical problems. Females with the condition are usually taller than average, and their weight may be low in comparison to their height. They may have menstrual irregularities, and, although rarely exhibiting severe mental impairments, sometimes have an increased risk of learning disabilities, delayed speech, and language skills.
A similar range of body types and characteristics are present in both triple X and Klinefelter's syndrome. These include a lanky/youthful appearance, non-affectedness, or varying degrees of androgyny. Body types/characteristics often follow traits shown in family members who are unaffected. The additional X chromosome can come from either the maternal or paternal side. Although body types and characteristics are distinguishable in triple X, the condition is verified only by karyotype testing.
Most women with triple X have normal sexual development and are able to conceive children. A few may experience early onset of menstruation.
