Triple X Syndrome
 
Triple X Syndrome, also known as Trisomy X, is the occurrence of three X chromosomes in a human rather than two X chromosomes or one X and one Y. This condition is only present in females, and is relatively harmless. Some go their entire lives without even knowing they have it, as it cannot be diagnosed until later in life. Only minor abnormalities in physical appearance result from this disorder, though mental development can be prolonged because of it. The chance of having a child with Trisomy X is only one percent, though there is no way to know for sure whether or not your child has it until it is fully developed. One in one-thousand girls have this disorder, and five to ten children are born in the United States with it each year. In nineteen-fifty-nine, the first case of Triple X Syndrome was realized by Patricia A. Jacobs.
 
Patricia published the first case of a woman with forty-seven X chromosomes while she was in Scotland. She found that the disorder is not hereditary, but a random occurrence in the human genes. The Human Genome Project, the ongoing mapping of the human make-up, may help us to find more information about the coincidence.
 
Girls with the disorder are typically abnormally tall, and may have a smaller head size than normal. People with Trisomy X are more likely to have learning disabilities, to be delayed in developing motor skills, and in some cases are apt to kidney trouble, seizures, or emotional disorders. Because the symptoms are so varied and come into effect later in life, Trisomy X cannot be diagnosed until later in life. Fortunately, it does not require treatment or a cure.
 
There are few cases in which Triple X Syndrome is connected to mental of emotional problems throughout life. It’s only major effect on the body takes place during infancy and toddlerhood, through parts of childhood. The girl with the disorder may have difficulties learning how to speak, read, write, and even walk. However, she will most likely lead a normal adult life. The effects on the body are minor and sometimes unnoticeable. As mentioned above, the carrier may be unusually tall or have a small head. Sometimes the eyes will be abnormally far apart, and kidney problems or seizures may come up.
 
Triple X Syndrome is not a severe condition, and it does not require treatment, although it’s symptoms may. There is no cure for Trisomy X today.
 
Trisomy X is a genetic disorder, and is therefore not contagious. It cannot be passed like a cold, or from child to parent. It is a random happenstance in the formation of a child, and it is not severe, though it can contribute to severe health problems- development problems, kidney failure, seizures, emotional disorders. However, all of these can happen to someone who does not have Trisomy X. A male cannot have Trisomy X.
 
In conclusion, Trisomy X is not something one should be worried about. It is a minor disorder found in a small percent of women and it is not contagious or severe in any way. However, the Human Genome Project can help us learn more about it.
