Q87.3: Congenital malformation syndromes involving early overgrowth

You have a congenital disorder that has made you grow more than most people.

The condition can be hereditary. Other family members may also be affected by the disease.

Various hereditary diseases can make you grow more than usual. As an adult, you may therefore be taller than other people. However, you may also be of normal height. You may also have other symptoms. Some organs may be larger than normal, for example. Intellectual processing is sometimes affected in individuals with these diseases.

  • G: Confirmed diagnosis
  • V: Tentative diagnosis
  • Z: Condition after
  • A: Excluded diagnosis
  • L: Left
