The lifespan of people with Noonan's syndrome can be similar to the general population, however, Noonan syndrome can be associated with several health conditions that can contribute to mortality. The greatest contributor to mortality in individuals with Noonan syndrome is complications of cardiovascular disease.
Jacqueline Anne Noonan (October 28, 1928 – July 23, 2020) was an American pediatric cardiologist best known for her characterization of a genetic disorder now called Noonan syndrome. [ 1 ] [ 2 ] She was also the original describer of hypoplastic left heart syndrome .
Noonan syndrome with multiple lentigines (NSML) which is part of a group called Ras/MAPK pathway syndromes, [2] is a rare autosomal dominant, [3] multisystem disease caused by a mutation in the protein tyrosine phosphatase, non-receptor type 11 gene . The disease is a complex of features, mostly involving the skin, skeletal and cardiovascular ...

[1] [24] Optic disc drusen are not related to Bruch membrane drusen of the retina which have been associated with age-related macular degeneration. [6]
Noonan syndrome with multiple lentigines (NSML), formerly called LEOPARD syndrome SYNGAP1-related intellectual disability Somatic mutations in the Ras/MAPK pathway can cause cancers and disorders such as RAS-associated autoimmune leukoproliferative disorder (RALD) or juvenile myelomonocytic leukemia (JMML).
