Patterson-Stevenson-Fontaine Syndrome

Patterson-Stevenson-Fontaine syndrome is a very rare syndrome characterized by abnormal development of the bones and tissues of the face (mandibulofacial dysostosis) and limb abnormalities. Physical features of this condition may include a recessed jaw (retrognathism), cleft palate, and anomalies of the external ears. Limb abnormalities may include the absence of toes, clefts in the feet, and fusion of toes together (syndactyly). These limb abnormalities together are known as split-foot deformity or ectrodactyly. 

Patterson-Stevenson-Fontaine syndrome is inherited in an autosomal dominant manner. Diagnosis of the condition may be based on seeing symptoms in an individual that are consistent with the syndrome. Treatment is focused on improving the symptoms of each person.
