Cardio‐facio‐cutaneous (CFC) syndrome — a distinct entity? Report of three patients demonstrating the diagnostic difficulties in delineation of CFC syndrome

We report on three patients with probable cardio-facio-cutaneous (CFC) syndrome. They present clinical findings of this condition such as: growth failure, heart defects, typical craniofacial appearance, ectodermal abnormalities, and developmental delay. We also give a detailed review of the previously published articles on CFC syndrome and discuss the differences between CFC, Noonan, and Costello syndromes. Other differential diagnoses are considered.
