Individuals with LPIN2-related Majeed syndrome typically experience multisystem inflammatory symptoms, including chronic sterile multifocal osteomyelitis, recurrent bone pain, recurrent fever, failure to thrive, dyserythropoietic anemia, and neutrophilic dermatosis. Recurrent bone pain is frequently localized near the joints, often of the long bones of the lower extremities. Recurrent osteomyelitis with joint swelling can lead to subsequent joint contractures. Congenital dyserythropoietic, microcytic anemia can range from mild to severe and sometimes requires blood transfusion. Neutrophilic dermatosis typically presents as transient painful erythematous plaques, pustules, or nodules with neutrophilic infiltrates. Other features of LPIN2-related Majeed syndrome include the development of hepatosplenomegaly and gastrointestinal symptoms, such as recurrent abdominal pain and/or recurrent diarrhea. As more families are being described, individuals with milder features are now being recognized.

Majeed syndrome is a rare condition that is characterized by recurrent episodes of fever and inflammation. Inflammation is a normal immune system response to injury and foreign invaders (such as bacteria). However, Majeed syndrome causes abnormal inflammation that can damage the body's tissues, particularly the bones and, less commonly, the skin. The signs and symptoms of Majeed syndrome typically appear in infancy or early childhood and can vary from person to person.

One of the major features of Majeed syndrome is an inflammatory bone condition known as chronic recurrent multifocal osteomyelitis (CRMO). This condition causes recurrent episodes of bone pain and joint swelling. These symptoms continue into adulthood, although they may improve for short periods. CRMO can lead to complications such as slow growth and the development of joint deformities called contractures, which restrict the movement of certain joints.

Another feature of Majeed syndrome is a blood disorder called congenital dyserythropoietic anemia. This disorder is one of many types of anemia, all of 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. This can cause tiredness (fatigue), weakness, pale skin, and shortness of breath. The complications of congenital dyserythropoietic anemia can range from mild to severe.

Some people with Majeed syndrome develop an inflammatory disorder of the skin 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.  https://medlineplus.gov/genetics/condition/majeed-syndrome
