Noonan syndrome facts*

*Noonan syndrome facts medical author:

  • Noonan syndrome is a genetic disorder that may cause short stature, distinctive facial features and heart abnormalities.
  • Aside from face and heart abnormalities, there may be associated bleeding abnormalities, scoliosis, infertility in males, lymphedema, and intellectual disability.
  • It is inherited as an autosomal dominant disease, meaning that the abnormal gene is on a non-sex chromosome and requires just one of two inherited genes to be abnormal.
  • The syndrome may also occur by a spontaneous mutation of the gene involved.
  • Since it is a genetic disease, there is no cure.
