Triple X syndrome, also called trisomy X or 47,XXX, is a genetic condition where a person is born with an extra X chromosome.
Normally, females have two X chromosomes (46, XX), but in Triple X Syndrome, an additional X chromosome is present (47, XXX). This condition is typically not inherited but instead occurs as a random event during the formation of eggs or sperm.
Most females with trisomy X live normal lives, although their socioeconomic status is reduced compared to the general population. Trisomy X occurs via a process called nondisjunction, in which normal cell division is interrupted and produces gametes with too many or too few chromosomes.
Generally, each person has one pair of sex chromosomes in each cell. The presence of an extra X chromosome in each of a female’s cells is known as trisomy X, commonly known as triple X syndrome, 47, or XXX.
Triple X Syndrome, also known as Trisomy X, is a genetic condition affecting females. Learn about its causes, symptoms, diagnosis, and how it may impact development and overall health.
Triple X syndrome is random and unpreventable. Even if you have a triple X chromosome, it won't usually be passed down to your children.
Triple X syndrome, also called trisomy X or 47,XXX, is characterized by the presence of an additional X chromosome in each of a female's cells. Although females with this condition may be taller than average, this chromosomal change typically causes no unusual physical features.
