Noonan Syndrome occurs in approximately 1 in 1,000 to 2,500 live births. The prevalence can vary depending on the population studied. It is a genetic disorder caused by mutations in various genes, most commonly the PTPN11 gene. Because it can manifest with a range of symptoms, some cases may go undiagnosed, potentially affecting the reported prevalence.

What are the causes of Noonan syndrome?
Noonan syndrome is usually caused by genetic mutations that affect proteins involved in signaling pathways that regulate cell growth and development. Most cases are sporadic, but some can be inherited in an autosomal dominant pattern. Mutations in genes such as PTPN11, SOS1, and RAF1 have been associated with Noonan syndrome.
What gene or chromosome is affected by noonan syndrome?
Noonan syndrome is primarily caused by mutations in the PTPN11 gene, located on chromosome 12. This gene provides instructions for making a protein involved in cell signaling and development. Changes in this gene can disrupt normal cell signaling pathways and lead to the characteristic features of Noonan syndrome.
