MOMO syndrome, a condition described in three earlier patients, is a constellation of macrosomia, obesity, macrocephaly, and ocular abnormalities as the main findings. We report a 6-year-old child with these findings as well as significant developmental issues, delayed bone age, clavicular pseudoarthrosis, and straight femurs. We believe that this child should be considered as having MOMO syndrome. Careful consideration of his facial features shows some overlap with Kabuki syndrome. Description of this case may help to better elucidate the clinical features of MOMO syndrome.
