What is Klinefelter Syndrome?

Klinefelter syndrome is a genetic disorder that affects roughly one out of every 1,000 males. It occurs when a boy is born with one or more extra X chromosomes. Normally, boys have one Y chromosome and one X chromosome. Though often not diagnosed until adulthood, the presence an extra X chromosome can cause unusual physical traits.

What causes Klinefelter syndrome?

The existence of an extra chromosome in a male typically happens when the genetic material in the egg splits unevenly during conception. Klinefelter syndrome stems from a random genetic event, and it is not passed down through families.

What are the symptoms?

Symptoms of Klinefelter syndrome vary, though many men who have it do not have obvious symptoms. However, for others, the condition can have a noticeable effect on growth or appearance such as sparse body hair, enlarged breast tissue, increased abdominal fat and reduced muscle mass. Some boys with Klinefelter syndrome may have language and learning problems. Adult males tend to be infertile.

When/how is it diagnosed?

Klinefelter syndrome usually is not diagnosed until the time of puberty when the testicles fail to grow normally. If you’re concerned your son or you may have Klinefelter syndrome, consult a physician. He or she will do a thorough physical exam and a chromosome test (called a karyotype) to determine if the condition is present.

If you have the ability to go early in the morning, I think that’s the only way you’ll avoid a multi-hour wait. Arrived at 6:50AM (doors open at 8AM, by that time there were 60+ people in line) and I was the ~20th person camping out in line. Got in the door at 8:40AM. Waited for a few minutes in the waiting room while they took my information. Test itself was quick (

Courteous. Efficient. Competent.

I came in for a cut and they took care of me quickly. Place was very clean, too.

The last thing I wanted to do was go into a medical facility right now. I very much appreciated how professional yet human they were. Thanks to Tara and the whole team there. Doing a great job.
