Overview

Triple X syndrome is a rare genetic condition that affects only people assigned female at birth (AFAB). It’s also called trisomy X syndrome or 47,XXX.

People are usually born with 46 chromosomes arranged in 23 pairs. (Chromosomes are the structures that carry your genetic information.) One copy of each chromosome in the pair comes from the egg, and the other copy in the pair comes from the sperm.

Usually, people have two sex chromosomes. Males have one X and one Y. Females have two Xs. But in triple X syndrome, all or some of your cells have three X chromosomes. If only some of your cells carry the extra X, it’s called 46,XX/47,XXX mosaicism.

If you have trisomy X, you may not notice any symptoms. Or you might be taller than your peers. You might have difficulty getting pregnant or have early menopause, but many people with this condition don’t.

How common is triple X syndrome?

The condition occurs in about 1 in 900 to 1,000 live births. This means that, in the United States, five to 10 people are born with triple X syndrome every day. It’s also likely that we don’t have good numbers for this syndrome because many people who have it never have any symptoms — so they never get tested.

Complications

Blood clots are a dangerous complication of atrial fibrillation (AFib). Blood clots can lead to stroke.
The risk of stroke from AFib increases as you grow older. Other health conditions also may increase the risk of a stroke due to AFib. These conditions include:
  • High blood pressure.
  • Diabetes.
  • Heart failure.
  • Some types of heart valve disease.
Blood thinners are commonly prescribed to prevent blood clots and strokes in people with atrial fibrillation.

Prevention

Healthy lifestyle choices can reduce the risk of heart disease and may prevent atrial fibrillation (AFib). Here are some basic heart-healthy tips:
  • Control high blood pressure, high cholesterol and diabetes.
  • Don't smoke or use tobacco.
  • Eat a diet that's low in salt and saturated fat.
  • Exercise at least 30 minutes a day on most days of the week unless your health care team says not to.
  • Get good sleep. Adults should aim for 7 to 9 hours daily.
  • Maintain a healthy weight.
  • Reduce and manage stress.
