17 Famous People With Klinefelter Syndrome or Marfan Syndrome

17 Famous People With Klinefelter Syndrome or Marfan Syndrome

Klinefelter syndrome (47, XXY) is a condition which occurs in men who have an extra X chromosome, resulting in an XXY sex chromosome karyotype.

The syndrome can affect different stages of the language, physical, and social development. It is estimated that 3,000 affected boys are born each year in the US.

Symptoms

The signs and symptoms of KS in young boys and teenagers may include:

  • a quiet character;
  • tall stature (short torso, long legs, and broader hips);
  • shyness;
  • small penis;
  • fatigue;
  • small, firm testicles;
  • weak bones;
  • gynecomastia (enlarged breast tissue).

Note – since KS can be hard to notice, many parents don’t know their child has the syndrome until he shows delays in puberty.

People who have KS have an increased risk for autoimmune disorders, like – rheumatoid arthritis, lupus, and Sjogren’s syndrome. Also, the syndrome is linked with an increased risk for breast cancer, varicose veins, lung disease, extragonadal germ cell tumor, and osteoporosis.

Treatment

Testosterone therapy can help sufferers with many of the symptoms of KS, but the treatment should start at puberty.

Marfan Syndromehuman body

Marfan syndrome is an inherited disease which affects the body’s connective tissue, that provides the support, strength, and elasticity to blood vessels, cartilage, heart valves, tendons, and other important parts of the physical body.

This autosomal dominant condition occurs once in every 10,000 to 20,000 people. It is named after Antoine Marfan, a French doctor who first described the syndrome in 1896.

If you have MS, you have a 50:50 chance of passing on the condition to each of your children.

Symptoms

Common symptoms may include:

  • backward flow of blood through the aortic and mitral valves;
  • floppiness of the mitral valve;
  • tear (dissection) and widening (aneurysm) of the main artery;
  • nearsightedness (myopia);
  • dislocation of the lenses of the eyes (ectopia lentis);
  • protrusion of the chest wall (pectus deformity);
  • an abnormal side-to-side curvature of the spine (scoliosis);
  • overgrowth of the long bones of the legs and arms.

Note – because of the high degree of variability of the syndrome, many of these clinical characteristics can be present at birth or they can manifest later in childhood.

Diagnosis

It can be difficult to diagnose since many sufferers have only a few typical symptoms and no specific biochemical or histologic changes.
