Welcome to the Noonan Support Group (TNSSG).

Noonan Syndrome is a condition which affects both children and adults. It is often associated with congenital heart disease and short stature.

  • It is believed that 1 in 1,000 to 1 in  2,500 children worldwide are born with this condition.
  • Each day a child is born with the condition.
  • It's possible that  people carry the gene yet are undiagnosed.
  • Once affected, their is a 50/50 chance of passing the gene on to one or more of their children.
  • It can also occur sporadically, presumably due to a new mutation.

Often called a "hidden" condition, the children affected may have no obvious casual signs to the onlooker, but the problems may be many and complex with no clinical test available. This is a genetic condition that can affect the heart, growth, blood clotting, mental and physical development. Affected individuals may have behavior problems, learning difficulties and many other anomalies. Noonan Syndrome is one of the most common of those conditions associated with congenital heart abnormality.

Still its exact cause remains unknown.....
