Char syndrome

A rare, genetic, multiple congenital anomalies/dysmorphic syndrome characterized by the triad of patent ductus arteriosus (PDA), facial dysmorphism (wide-set eyes, downslanting palpebral fissures, mild ptosis, flat midface, flat nasal bridge and upturned nasal tip, short philtrum with a triangular mouth, and thickened, everted lips) and hand anomalies (aplasia or hypoplasia of the middle phalanges of the fifth fingers).
