What are the signs and symptoms of MOMO syndrome?

The most consistent features that have been reported in affected individuals are generalized obesity starting from early childhood; macrocephaly present either at birth or postnatally; ocular (eye) abnormalities (especially retinal or choroid coloboma); delayed bone age; and intellectual disability.[1]

Although intellectual disability has been present in all reported patients, the type and severity appears to be variable. Some affected individuals have also been described has having other features including autism; “schizoid” behavior; irritability; developmental delay; speech delay; anxiety; severe tactile defensiveness; and/or extreme sound sensitivity.

With regard to ocular (eye) abnornalities, all but one affected individual reportedly showed either unilateral or bilateral ocular coloboma, involving the choroid, retina, and/or optic nerve. Other reported ocular abnormalities include microphthalmia, nystagmus, and convergent strabismus.[1]
