Type : Phenotype, molecular basis known;
Alternative titles and symbols : Cbl mutation-associated syndrome; Cbl syndrome;
Description : Noonan syndrome-like disorder is a developmental disorder resembling Noonan syndrome
(NS1; 163950) and characterized by facial dysmorphism, a wide spectrum of cardiac
disease, reduced growth, variable cognitive deficits, and ectodermal and musculoskeletal
anomalies. There is extensive phenotypic heterogeneity and variable expressivity (summary
by Martinelli et al., 2010). Patients with heterozygous germline CBL mutations have
an increased risk for certain malignancies, particularly juvenile myelomonocytic leukemia
(JMML; 607785), as also seen in patients with Noonan syndrome (summary by Niemeyer
et al., 2010).;
Inheritance : Autosomal dominant;
Molecular basis : Caused by mutation in the Cas-Br-M murine ecotropic retroviral transforming sequence
homolog gene (CBL, 165360.0001);
Neoplasia : Increased susceptibility to juvenile myelomonocytic leukemia;
