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 ...
The deficiency may be genetic. Among children without growth hormone deficiency, short stature may be caused by Turner syndrome or Noonan syndrome, chronic kidney disease, being small for gestational age at birth, Prader–Willi syndrome, Wiedemann-Steiner syndrome, or other conditions.
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 .
It is a feature of Turner syndrome [1] (only found in girls) and Noonan syndrome, [2] as well as the rarer Klippel–Feil syndrome, [3] or Diamond–Blackfan anemia. [ 4 ] References
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).
Cherubism has also been found combined with other genetic disorders including Noonan syndrome, Ramon syndrome, and fragile X syndrome. [8] Mutations of the SH3BP2 gene are only reported in 75% of Cherubism cases. [3] The mutation of the SH3BP2 gene is believed to increase production of over active proteins from this gene.
