What is Triple X Syndrome?

Triple X Syndrome is also known as triplo-X, XXX syndrome, 47, XXX aneuploidy or Trisomy X and it is mainly due to an extra x- chromosome, which is an abnormal thing. Chromosomes are described to have a rod like kind of structure and are normally present in the cellular nucleus found in the person’s body.

It is where the genetic information is stored. Females are usually the only ones affected by this kind of disease syndrome. It is usually the result of the formation of the father’s sperm cell or the mother’s egg cell. It is caused by an error upon the embryo’s developmental stage. It is a rare genetic problem occurrence, which occurs in approximately 1 in every 1,000 of the female population. It is not easily diagnosed until reaching later in life.

Normally, a person has 23 chromosomal pair or otherwise known as the sex chromosomes which will have the final say of what the person gender would be. Female babies usually have XX chromosome pair while Male babies have XY chromosome pairs. Both babies’ mother and the father contribute to the chromosomal pair and to their gender. The father can contribute the X or Y chromosome while the mother can only contribute the X chromosome. Babies or individual persons who have the triple x syndrome it may be due to:



  1. Mosaic form of triple x syndrome or there is an error in the embryo development. The error happens after the egg and the sperm is fertilized and before the development of the embryo.
  2. Nondisjunction or either the mother’s egg or the father’s sperm was not properly formed. It occurs in the sperm cell or egg cell production, wherein there is a cellular division error which occurs randomly.

One must take note that this kind of disease syndrome is not due to an inherited condition. It happens in the rarest occurrence. And it only happens with females. As mentioned, another name for this disease syndrome is 47, XXX syndrome due to the fact that the person has an extra X chromosome which resulted to the 47 chromosomes, which should be normally 46 chromosomes.

  • Amniocentesis – What happens here is that the amniotic fluid, where the baby, embryo or fetus floats, is collected and further examined.
  • Blood Test – This is done if the physician notices, upon physical assessment, physical developmental delays.
  • Genetic testing called Karyotyping – This is done to detect if really the female person has the extra X chromosome.

Triple X Syndrome Treatment
