TRIPLE X SYNDROME
AND CAUSES.
WHAT IS A TRIPLE X SYNDROME?
This syndrome is an abnormality in the X
chromosome and for that reason it only afects
women. Normally the woman have a couple of X chromosome, but in this case, they have 2 of this
chromosomes.

WHAT IS A TRIPLE X SYNDROME?
The article says very clearly that this kind of syndrome is not a heritage, it’s just a mistake in the formation of the father sperm cell or the mothers egg.
It is possible too that this syndrome is only that
something went wrong in the develompent of the embryo.
WHAT IS A TRIPLE X SYNDROME?There is no clear visual difference betwen a female with the syndrome and the other females, just in some cases they can be taller than the normal women.
WHAT IS A TRIPLE X SYNDROME?
• Intelligence may be at the lower range of normal, stature is usually tall, there may be speech and behavioral problems. The outstanding feature of the syndrome is the occurrence of twin Barr bodies in a typical cell.
OBSERVATION
• It is important to know about this syndromes, because although it does not affect a lot of women we could have one of the few ones and we have to know how to do the treatment.

Chromosome regions that are prone to
breakage are a rich source of genetic
variation.

The functions of this new parts are
different of the others, so the chromosomal
organization plays an important role.

CHROMOSOME BREAKPOINTS CONTRIBUTE TO GENETIC VARIATION.The new combinations begin with the “crossing over” of segments of maternal and paternal chromosomes to form hybrid chromosomes has been acknowledge as a driver of genetic variation.
OSERVATION
• The chromosome breakage in evolution has helped to confirm the importance of the chromosomal organization, because one little change can make a totally new kind. This kind of studies can help us to understand the genetic variation.
MEDICAL UTILITY
MEDICAL UTILITY
• The principal utility of this investigations is the the big importance in the advance of the genetic studies.
MEDICAL UTILITY
• The medicine is going to be something easier for the pacients, because with de advanced studies, is going to be more safe to do the treatments and identify the variations in the phenotype and genotype.
