Summary Summary

Majeed syndrome is characterized by recurrent episodes of fever and inflammation in the bones and skin. The two main features of this condition are chronic recurrent multifocal osteomyelitis (CRMO) and congenital dyserythropoietic anemia (CDA). CRMO causes recurrent episodes of pain and joint swelling which can lead to complications such as slow growth and the development of joint deformities called contractures. CDA involves a shortage of red blood cells which can lead to fatigue (tiredness), weakness, pale skin, and shortness of breath. Most people with Majeed syndrome also develop inflammatory disorders of the skin, most often a condition known as Sweet syndrome. Majeed syndrome results from mutations in the LPIN2 gene. This condition is inherited in an autosomal recessive pattern.^[1]

Symptoms Symptoms

Majeed syndrome is characterized by recurrent episodes of fever and inflammation in the bones and skin. There are two main features of Majeed syndrome:^[1]

Chronic recurrent multifocal osteomyelitis (CRMO), an inflammatory bone condition which causes recurrent episodes of pain and joint swelling. These symptoms begin in infancy or early childhood and typically persist into adulthood, although there may be short periods of improvement. CRMO can lead to complications such as slow growth and the development of joint deformities called contractures, which restrict the movement of certain joints.
Congenital dyserythropoietic anemia is a blood disorder which involve a shortage of red blood cells. Without enough of these cells, the blood cannot carry an adequate supply of oxygen to the body's tissues. The resulting symptoms can include tiredness (fatigue), weakness, pale skin, and shortness of breath. Complications of congenital dyserythropoietic anemia can range from mild to severe.

Most people with Majeed syndrome also develop inflammatory disorders of the skin, most often a condition known as Sweet syndrome. The symptoms of Sweet syndrome include fever and the development of painful bumps or blisters on the face, neck, back, and arms.^[1]

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

Cause Cause

Majeed syndrome is caused by mutations in the LPIN2 gene. This gene provides instructions for making a protein called lipin-2. Researchers believe that this protein may play a role in the processing of fats. It may also be involved in controlling inflammation and play a role in cell division. Mutations in the LPIN2 gene alter the structure and function of lipin-2. It is unclear how these genetic changes lead to bone disease, anemia, and inflammation of the skin in people with Majeed syndrome.^[1]

Inheritance Inheritance

Majeed syndrome is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene. Although carriers typically do not show signs and symptoms of the condition, some parents of children with Majeed syndrome have had an inflammatory skin disorder called psoriasis.^[1]

Diagnosis Diagnosis

Making a diagnosis for a genetic or rare disease can often be challenging. Healthcare professionals typically look at a person’s medical history, symptoms, physical exam, and laboratory test results in order to make a diagnosis. The following resources provide information relating to diagnosis and testing for this condition. If you have questions about getting a diagnosis, you should contact a healthcare professional.

Testing Resources

The Genetic Testing Registry (GTR) provides information about the genetic tests for this condition. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional.

Treatment Treatment

Treatment is based upon the symptoms present. Chronic recurrent multifocal osteomyelitis (CRMO) is treated with nonsteroidal anti-inflammatory drugs (NSAIDs) and physical therapy to avoid disuse atrophy of muscles and contractures. If CRMO does not respond to NSAIDs, corticosteroids can be used short term to control CRMO and skin manifestations. Resolution of bone inflammation has been reported in at least two children who were treated with an IL-1 inhibitor. Congenital dyserythropoietic anemia (CDA) may be treated with red blood cell transfusion.^[2]
