Comment

Characteristic findings in patients with Noonan syndrome are the facial anomalies: hypertelorism, down-slanting palpebral fissures, high-arched eyebrows, epicanthal folds, full upper-lip, depressed nasal root with a wide nasal base and low-set ears with thickened helices; webbed neck, the skeletal anomalies with short stature, pectus excavatum and cubitus valgus; congenital heart disease (pulmonary valve stenosis is most common), abnormalities in the lymphatic system (e.g. lymphedematous legs and probably also the cause of the neck webbing), and mild mental retardation. LEOPARD syndrome is now regarded as being part of Noonan syndrome.

Several malignancies have been reported in this disorder [for a review, see: 30 and 37], most commonly myeloproliferative disorders[1,2,10-16]: mainly chronic myeolomonocytic leukemia / juvenile myelomonocytic leukemia (JMML) and acute lymphoblastic leukemia. JMML in NS carries a relatively benign course. Other tumors reported in Noonan syndrome are central giant cell granuloma of the right maxillary sinus[3], cavernous hemangioma of the brain[4], astrocytoma [31,32] rhabdomyosarcoma[17,28,34], malignant schwannoma[27], pheochromocytoma[28], medulloblastoma [38], ganglioneuroma, intracranial chondroma[9], hepatoblastoma[8], juvenile papillomatosis of the male breast[16], granular cell tumor of the scrotum[19] and multiple subcutaneously[33,34], Hodgkin disease[20] and neuroblastoma[21,23,24], seminoma[25] and non-seminoma testis[26], Sertoli cell tumor of the testis[34] and Wilms tumor[30].

Swanson et al[22] observed that SOS1 is not a significant human oncogene in most cancers, and suggested that Noonan syndrome patients with SOS1 mutations may not be at increased risk of developing cancer. However, some tumors have been reported in these patients[34]: embryonal rhabdomyosarcoma, Sertoli cell testis tumor, granular cell tumors of the skin and a lesion suggestive for a giant cell tumor. De Philippi et al[29] reported a child with a germline NRAS mutation, JMML and dysmorphic feature that did not meet the Noonan syndrome clinical criteria. JMML and Noonan-like features have been observed in patients with germline CBL gene mutations [35,36]

Some patients with neurofibromatosis type 1 (NF1) have facial features resembling those of Noonan syndrome patients. Probably most are to be regarded as a having variant of NF1, associated with germline NF1 gene mutations[18]. As in Noonan syndrome, ALL has been reported in patients with the NF-Noonan disorder[7]. LEOPARD syndrome is now regarded to be part of Noonan syndrome.
