As you can see XYY syndrome is a rare genetic disorder. XYY syndrome occurs in about 1 in 1,000 newborn boys. I guess that you can say that I am lucky but I do not see it that way. Five to ten boys with XYY are born in the United States each day. Normal people have 46 chromosomes in each cell. Two of the 46 chromosomes, known as X and Y, are called sex chromosomes because they help determine whether a person will develop male or female sex characteristics. Females typically have two X chromosomes (46,XX), and males have one X chromosome and one Y chromosome. However, I have 2 Y chromosomes instead of 1.

I live an everyday life just like other guys my age. I wonder if this disorder will ever go away. XYY syndrome occurs 1 in 700 male births. When it becomes the time for me to have children I hope that this will not affect them. I have reduced fertility and I am six-foot four. Basketball coaches tell me all of the time that I should try out for their team. Having a higher testosterone level sometimes makes me feel like a "bettter" man but deep down I know that I am just your average joe. I really think that I would like basketball but I am poorly coordinated.

Me again!
Well, today during computer class, instead of paying attention I wanted to research my genetic disorder. This disorder I have is not as serious as other genetic disorders out there. However, I still feel different and out of place at school. I found out that most men never find out that they have XYY syndrome so I guess you can say that I am lucky. I also found that there really isn't a specific tratment for me to take. The only thing that I can do to help myself is to speech, physical, and occupational therapy!! Like that's going to help!

Hi, my name is Matt and I have XYY syndrome. I have created this blog to show my viewers about my genetic disorder and write out my feelings. If anyone is listening or has anything to say that might help me please comment back!! I am 15 years old and going to school and trying to be "normal" is a hard job. XYY syndrome is a rare chromosomal disorder that affects just males. Most males have normal chromosomes which include one X and one Y but some how and some way I got "lucky" with an extra Y.

Everyone at school looks at me weird. I am tall and thin and have bad acne:( I always try to get girls but they don't dig the XYY thing. I am ashamed of it and don't tell anyone about it. My mom always says that I have antisocial behavior but I guess that's normal for a person with XYY syndrome. I also have learning/intelligence disabilities. I am doing good in school just to get a B. I have a younger sister named Kayla who is so sweet and smart. My IQ is about 10-15 points lower than hers just because of my genetic disorder.

Well I thought I would post this so that everyone can read it. Please help me!! Respond! Over and out
