Michels syndrome

Autosomal recessive - en

Michels syndrome is a rare genetic disorder characterized by a combination of craniofacial abnormalities, ocular defects, and skeletal anomalies. It is also known as Blepharo-naso-facial syndrome. The syndrome is named after the French ophthalmologist Robert Michels, who first described the condition.

Clinical Features

Individuals with Michels syndrome typically present with a distinct set of clinical features, which may include:

• Blepharophimosis: A condition where the eyelids are abnormally narrow horizontally.
• Ptosis: Drooping of the upper eyelid.
• Epicanthus inversus: A fold of skin that runs from the lower eyelid upwards towards the inner corner of the eye.
• Telecanthus: An increased distance between the inner corners of the eyes.
• Hypertelorism: An abnormally increased distance between the eyes.
• Nasal anomalies: Including a broad nasal bridge and a short nose.
• Cleft lip and palate: A split in the upper lip and/or the roof of the mouth.
• Micrognathia: A condition where the jaw is smaller than normal.
• Skeletal anomalies: Such as short stature and limb abnormalities.

Genetics

Michels syndrome is believed to follow an autosomal dominant inheritance pattern, meaning a single copy of the altered gene in each cell is sufficient to cause the disorder. However, the specific gene or genes involved have not been definitively identified.

Diagnosis

The diagnosis of Michels syndrome is primarily based on clinical evaluation and the identification of characteristic physical features. Genetic testing may be used to confirm the diagnosis and to differentiate it from other syndromes with overlapping features.

Management

There is no cure for Michels syndrome, and treatment is generally symptomatic and supportive. Management may include:

• Surgical correction of craniofacial anomalies, such as ptosis and cleft lip/palate.
• Orthodontic treatment for dental anomalies.
• Vision therapy for ocular defects.
• Speech therapy for individuals with speech difficulties due to cleft palate.

Prognosis

The prognosis for individuals with Michels syndrome varies depending on the severity of the symptoms and the presence of any associated complications. With appropriate medical care and surgical interventions, many individuals can lead relatively normal lives.
