this exceptionally rare syndrome was first described in 1993
the case reports described two unrelated patients, a boy and a girl, with an overgrowth syndrome and the following common characteristics:
macrocrania
obesity
ocular abnormalities (retinal coloboma and nystagmus), downward slant of palpebral fissures, mental retardation, and delayed bone maturation
the authors suggested that this syndrome is due to a new autosomal dominant mutation and propose to designate it with the acronym of "MOMO syndrome" (Macrosomia, Obesity, Macrocrania, Ocular anomalities)
