Opitz-Kaveggia syndrome/FG syndrome
Background
FG syndrome: Opitz-Kaveggia syndrome; Opitz FG syndrome; Keller syndrome
FG syndrome was first described by Professor Opitz and Dr Kaveggia in 1974. It became known as FG syndrome according to the system used at that time by Dr Opitz, who preferred to name conditions with the initials of the names of the first presenting families, rather than eponymously, after the name of the doctors who wrote the first medical reports. Nevertheless, the Opitz-Kaveggia name is now preferred by some doctors and the name Keller syndrome is a name that is seldom used. Note Opitz-Kaveggia/FG syndrome has subtle clinical and important genetic differences from the Opitz G/BBB syndrome.
