Triplo X Syndrome is a chromosomal abnormality that affects females. Females normally have two X chromosomes; however, those with Triplo X Syndrome carry three X chromosomes (trisomy X) in the nuclei of body cells. No specific pattern of symptoms and malformations (phenotype) has been found to be associated with this abnormal chromosomal make-up (i.e., 47,XXX karyotype). Many affected females appear to have no or very few associated symptoms, while others may have various abnormalities.
However, investigators indicate that Triplo X Syndrome is a relatively common cause of learning difficulties, particularly language-based disabilities (e.g., dyslexia), in females. Evidence suggests that affected females typically have normal intelligence with IQs that tend to be lower than that of their brothers and sisters (siblings). Mental retardation rarely occurs. Infants and children with Triplo X Syndrome may tend to have delayed acquisition of certain motor skills and delayed language and speech development.
Affected females often are of tall stature. According to researchers, although sexual development and fertility are usually normal, some may have delayed puberty and/or fertility problems. In addition, in some cases, certain physical abnormalities have been reported, such as a relatively small head, vertical skin folds that may cover the eyes' inner corners (epicanthal folds), and/or other findings. Triplo X Syndrome results from errors during the division of reproductive cells in one of the parents.

To answer your question, tomel, I'm not sure what is Fragile X. Basically, she was born with an extra X chromosome. Girls are normally XX, she is XXX.
Thank you for taking the time research anxiousmomtobe. I will make a note of all the info.
I read a little about it on the internet but I was looking to hear from people who have a child with this disorder. Just wanna hear about your experiences and the ways you've coped with the situation.
hi Raine Although I do not have a child with Fragile X (my child has Autism ) i am a special ed teacher and have a student who has fragile X. He is 16 and is able to read at a first grade level. he can talk fairly well and is able to care for personal hygiene rather well. i do believe you mentioned that your friend has a daughter and with all the research that i have done; Fragile X effects boys to a more severe degree than girls simply because the XYX (male fragile X) is much more sensitive to more problems ( behaviors and the like). Your firends daughter has an wonderful chance to function like other children. I will tell you that the best thing you can do for yuor friend is be POSITIVE and when and ifthere are problems and she's stressed out reminder her of all the things that her daughter can do because she will and i say this from experince get down about how functional her daughter is. Please reminder that in life its the little things that count and for me athough I do wish that my daughter did not have Autism I will say that my princess is the light of my life and each day she is a consistant reminder that she is happy and I wish that I could be happy like that. and i strive to be that happy. Good Luck to you and your friend,
Thanks for the kind words. We will be very supportive of her and treat her daughter like she was our own. She is God's creation.
Hello, my name is Brandon, and I have a question for you, i had a sister that passed away at birth, her spinal cord wasn't attached to her brain, if she had lived, she would have been mentally and phisically handicapped, do you know the reason for this abnormality? If you do, i would greatly appreciate it if you would tell me, thank you
Hello, this i Brandon again, I know a girl at my high school by the name of Olivia Lawrence, she has Rett syndrome, I would like to know, would Rett syndrome be caused by having Triplo X chromosomes, because I would really like to know, if you could tell me the if this is caused by having Triplo X chromosomes, I would really appreciate it, thanks again
