Description
What is 3MC Syndrome 2?
3MC Syndrome 2, also known as Carnevale-Mingarelli-Malpuech-Michels Syndrome 2, is a rare autosomal recessive disorder that is part of the broader category of 3MC syndromes. This condition is characterized by a range of developmental anomalies and distinctive facial features.
Key Features:
- Facial Dysmorphism: The main feature of 3MC Syndrome 2 is facial dysmorphism, which includes:
- Hypertelorism (widely spaced eyes)
- Blepharophimosis (narrowing of the eye opening)
- Blepharoptosis (droopy eyelids)
- Highly arched eyebrows
- Other Tissue and Organ Problems: In addition to facial features, 3MC Syndrome 2 can also affect other tissues and organs, including:
- Craniosynostosis (premature closure of the skull bones)
- Learning disability
- Genital abnormalities
- Limb anomalies
- Vesicorenal problems
Causes:
The exact cause of 3MC Syndrome 2 is a mutation in the COLEC11 gene, which is located on chromosome 2p25. This genetic mutation leads to the development of the characteristic facial features and other tissue and organ problems associated with this condition.

Signs and Symptoms
Common Features of 3MC Syndrome
Three M syndrome, also known as 3MC syndrome, is a rare genetic disorder characterized by several distinct physical and developmental features. Some of the common signs and symptoms of this condition include:
- Facial Dysmorphism: Individuals with 3MC syndrome often exhibit facial abnormalities such as hypertelorism (increased distance between the eyes), blepharophimosis (drooping eyelids), blepharoptosis (eyelid drooping), and highly arched eyebrows.
- Cleft Lip and Palate: Cleft lip and palate are also consistent findings in 3MC syndrome, occurring in approximately 40-68% of cases.
- Postnatal Growth Deficiency: Individuals with this condition often experience slow growth after birth, leading to short stature (dwarfism).
- Cognitive Impairment: Developmental delay and intellectual disability are common features of 3MC syndrome.
- Hearing Loss: Hearing loss is also a consistent finding in individuals with this condition.
Additional Symptoms
Other symptoms associated with 3MC syndrome include:
- Anterior Chamber Defects: Abnormalities in the anterior chamber of the eye
- Cardiac Anomalies: Congenital heart defects
- Caudal Appendage: A rare congenital anomaly where a small, usually non-functional, piece of tissue is attached to the lower back
- Umbilical Hernia/Omphalocele: Abnormalities in the umbilical cord or navel area
These symptoms can vary in severity and may not be present in every individual with 3MC syndrome.

Diagnostic Tests
Diagnostic Tests for 3MC Syndrome
3MC syndrome, also known as Malpuech syndrome, is a rare genetic disorder characterized by unusual facial features and problems affecting other tissues and organs. Diagnostic testing plays a crucial role in identifying the condition and informing prognosis and clinical management.
- Genetic tests: Targeted mutation analysis, mutation scanning/screening, and sequence analysis of selected exons are used to identify mutations in the COLEC
Additional Diagnostic Tests
- Targeted mutation analysis
- screening
- sequence analysis of selected exons
Treatment
Treatment Options for 3MC Syndrome
According to various sources, treatment for 3MC syndrome includes supportive care, pharmacological treatment, surgery, and rehabilitation.
- Supportive Care: This involves providing emotional support and managing symptoms such as cleft lip and/or palate, craniosynostosis, and other developmental anomalies.
- Pharmacological Treatment: While there are no specific medications approved for 3MC syndrome, treatments may include nocturnal mouthpiece ventilation to manage obstructive sleep apnea [10].
- Surgery: Surgical interventions may be necessary to correct physical abnormalities such as cleft lip and/or palate, craniosynostosis, and other developmental anomalies.
- Rehabilitation: Rehabilitation therapies such as speech therapy, occupational therapy, and physical therapy may be necessary to help individuals with 3MC syndrome develop the skills they need for daily living.
It's essential to consult with a healthcare professional for medical advice and treatment [6].

Differential Diagnosis
Differential Diagnosis of 3MC Syndrome
Three M syndrome (3MC) is a rare genetic disorder characterized by short stature, characteristic abnormalities of the head and face, and other physical features [5]. When considering the differential diagnosis for individuals with suspected 3MC syndrome, several conditions should be taken into account.
- Syndromic craniosynostosis: This condition involves premature fusion of the bones in the skull, leading to abnormal head shapes and facial features. Crouzon disease is a type of syndromic craniosynostosis that can present with similar symptoms to 3MC syndrome [1][7].
- Acrofrontofacionasal dysostosis: This rare genetic disorder affects the development of the face, hands, and feet, leading to characteristic physical features. It has been included in the differential diagnosis for 3MC syndrome due to its overlapping symptoms [4][8].
- Autosomal recessive Robinow syndrome: This is a rare genetic disorder characterized by short stature, facial abnormalities, and other physical features that can be similar to those seen in 3MC syndrome [4][8].
Other Conditions
In addition to these specific syndromes, individuals with suspected 3MC syndrome should also be considered for other conditions that may present with similar symptoms. These include:
- COLEC10-related 3MC syndrome: This is a rare genetic disorder caused by mutations in the COLEC10 gene. It can lead to short stature, radioulnar synostosis, cleft lip and palate, and other physical features [6][9].
- Radioulnar synostosis: This condition involves the premature fusion of the radius and ulna bones in the forearm, leading to abnormal bone growth and development.
