Article Abstract
Background: MOMO syndrome is a rare disorder with variable presentation and unknown etiology belonging to the overgrowth syndromes group.
Case Presentation: The authors describe a patient presenting with severe developmental delay, absent speech, autism spectrum disorder, central nervous system malformations, bilateral optic atrophy, and postnatal overgrowth, besides a dysmorphic and progressive coarse face. A clinical diagnosis of MOMO syndrome was proposed, but he developed megaesophagus, megacolon, paraparesis, and severe acne during the clinical follow-up, which are not described in this condition. Whole-genome sequencing detected a deletion of 11.9 Mb at 3q13.2q21.2 comprising 80 genes, including the gene associated with Primrose syndrome.
Conclusion: Despite the atypical manifestations in this patient, the overlapping features between MOMO syndrome, Primrose syndrome, and 3q13.31 deletion led the authors to propose that MOMO syndrome could be part of the Primrose/3q13.31 microdeletion syndrome spectrum.

Article Synopsis
- MOMO syndrome is a rare overgrowth disorder with uncertain causes and varied symptoms, including developmental delays and facial dysmorphism.
- In a case study, a patient exhibited severe developmental issues and atypical symptoms like megaesophagus and severe acne, alongside the typical signs of MOMO syndrome.
- Researchers suggest that the overlap of symptoms between MOMO syndrome, Primrose syndrome, and specific genetic deletions indicates that MOMO could be considered part of a broader microdeletion syndrome spectrum.

MOMO is an acronym for macrosomia, obesity, macrocephaly and ocular abnormalities. The syndrome was first described in 1993, with a total of nine patients published thus far. All the cases presented intellectual disability and in one case autism was described.

Macrosomia, obesity, macrocephaly, and ocular abnormalities syndrome (MOMO syndrome) has been reported in only four patients to date. In these sporadic cases, no chromosomal or molecular abnormality has been identified thus far. Here, we report on the clinical, cytogenetic, and molecular findings in a child of healthy consanguineous parents suffering from MOMO syndrome.

MOMO syndrome, previously defined as Macrosomia, Obesity, Macrocephaly, and Ocular abnormalities (OMIM 157980) is a rare intellectual disability syndrome of unknown cause. We describe two further patients with MOMO syndrome. Reported data of patients with MOMO syndrome and our own findings indicate that overgrowth does not appear to be a specific feature.

There are multiple genetic disorders with known or unknown etiology grouped under obesity syndromes. Inspite of having multisystem involvement and often having a characteristic presentation, the understanding of the genetic causes in the majority of these syndromes is still lacking. The common obesity syndromes are Bardet-Biedl, Prader-Willi, Alstrom, Albright's hereditary osteodystrophy, Carpenter, Rubinstein-Taybi, Fragile X, and Börjeson-Forssman-Lehman syndrome.
