Comment

Hallmarks of CFCS are a typical facies, congenital heart defects (predominantly pulmonary stenosis and ASD), growth failure and ectodermal anomalies. There is clinical and molecular overlap with Noonan syndrome and Costello syndrome.These disorders share disruption of the RAS/MAPK signalling pathway.[1-5]. It has been suggested that patients with BRAF and MEK mutations should be diagnosed with CFC syndrome, and the diagnosis of Costello syndrome be reserved for patients with HRAS mutations[5]

Van den Berg and Hennekam[6] reported a 5-year-old girl with CFC and unknown mutation status, who was diagnosed with ALL. Makita et al[7] reported another case in a patient with a BRAF mutation. Bisogno et al[8] described a 20 months old boy with CFC, unknown mutation status, and an embryonal rhabdomyosarcoma. A hepatoblastoma in a MEK1 mutation CFC patient was reported by Al-Rahawan[9]. A 2-month-old child with NHL, CFC and a BRAF mutation was reported by Ohtake et al[10]. A recent review of te literature listed 4 cases of ALL, 2 of NHL, and 1 hepatoblastoma and 1 embryonal rhabdomyosarcoma each[11]. Hemangiomas are not uncommon in CFC[12].
