Noonan syndrome


Are there learning delays in Noonan syndrome?

Most children do well in a normal educational setting, but 25% have learning disabilities and 10% to 15% require special education. Intellectual abilities are mildly lowered in children with Noonan syndrome. IQ scores below 70 are seen in 6% to 23%

Articulation deficiency is also common in Noonan syndrome (72%) but usually responds well to speech therapy. Language delay may be related to hearing loss or articulation deficiencies. Children typically say their first words around 15 months and simple two-word phrases around age 31 to 32 months.

Speak to a genetic counselor or a medical geneticist to learn more about Noonan syndrome.
