What is Momo Syndrome?

Momo syndrome is a rare genetic disorder that combines several distinct symptoms. Understanding its characteristics and history is crucial for anyone interested in rare diseases.

  1. Definition and Acronym: Momo stands for Macrosomia, Obesity, Macrocephaly, and Ocular abnormalities. The name also nods to Momus, the tall and obese king of Carnivals.

  2. History of Diagnosis: Diagnosed first in 1993 by Professor Danilo Moretti-Ferreira, a Brazilian expert in genetic and clinical studies of neurodevelopmental disorders.

  3. Prevalence: Extremely rare, with only seven reported cases worldwide, occurring in about 1 in 100 million births.

Symptoms of Momo Syndrome

The symptoms of Momo syndrome are varied and can significantly impact the lives of those affected. Here are the primary symptoms:

  1. Macrosomia: Excessive birth weight, often noticeable at birth.

  2. Obesity: Generalized obesity that continues to develop as the child grows.

  3. Macrocephaly: An unusually large head size, often noticeable early in life.

  4. Ocular Abnormalities: Includes retinal coloboma and nystagmus, affecting vision.

  5. Mental Disability: Intellectual disability, impacting cognitive development.

  6. Downslanting Palpebral Fissures: Eyes slant downward, a distinct facial feature.

  7. Hypertelorism: Eyes spaced too far apart, another facial characteristic.

  8. Broad Nasal Root: A wider than usual nasal bone.

  9. High and Broad Forehead: A forehead that is both higher and broader than average.

  10. Delayed Bone Maturation: Slower bone development compared to peers.

Additional Clinical Signs

Beyond the primary symptoms, there are other clinical signs that can help in diagnosing Momo syndrome:

  1. Macrostomia: Larger than usual mouth size.

  2. Delayed Eruption of Teeth: Teeth take longer to come in.

  3. Tall Stature: Individuals are often taller than average for their age.

Understanding the Pathophysiology

The exact cause of Momo syndrome remains a mystery, but research provides some clues:

  1. Pathophysiology: Linked to a de novo autosomal dominant mutation, meaning it arises from a new mutation not inherited from parents.

  2. Inheritance Pattern: Suggested to be autosomal dominant, though an autosomal recessive pattern is also considered.

Diagnosing Momo Syndrome

Diagnosis involves observing specific signs and symptoms and ruling out other genetic conditions:

  1. Diagnosis: Based on clinical evaluation, focusing on macrocephaly, obesity, mental disability, and ocular abnormalities.

Documented Cases
