a) frontal b)lateral view of KBG syndrome individual-facial dysmorphisms including low frontal hairline, mild synophrys, hypertelorism
Symptomsmacrodontia, brachycephaly, hypertelorism, synophrys, long philtrum, thin upper lip
CausesANKRD11 gene mutation

KBG syndrome is a genetic disease that is the result of a mutation in the ANKRD11 gene at location 16q24.3.[1] Features include unusually large upper front teeth (macrodontia), wide, short skull (brachycephaly), widely spaced eyes (hypertelorism), and wide eyebrows that may grow together in the middle (synophrys).[2]

The syndrome was first described by Herrmann in 1975 in three distinct families.[3] Herrmann proposed the name KBG syndrome after the initials of affected families last names.[4]
