Noonan syndrome-like disorder with juvenile myelomonocytic leukemia
Synonyms: CBL syndrome | Noonan syndrome-like disorder with JMML
A rare genetic polymalformative syndrome characterized by a Noonan-like phenotype associated with increased risk of developing juvenile myelomonocytic leukemia (JMML). The Noonan-like (NS) phenotype includes dysmorphic facial features (i.e. high forehead hypertelorism downslanting palpebral fissures ptosis low-set ears prominent philtrum and short neck with or without pterygium colli) developmental delay hypotonia and small head circumference.
