HistoryThis section has been translated automatically.

Majeed et al. 1989

DefinitionThis section has been translated automatically.

Majeed syndrome is a rare inflammatory, autosomal recessive multisystem human disease associated with chronic multifocal osteomyelitis (CRMO) and congenital dyserythropoietic anemia (CDA) with or without neutrophilic dermatosis (Sweet syndrome).

Occurrence/EpidemiologyThis section has been translated automatically.

MJDS is extraordinarily rare. So far, only 24 individuals from 10 families with genetically confirmed Majeed syndrome have been described in the literature

EtiopathogenesisThis section has been translated automatically.

MJDS is associated with mutations in the LPIN2 gene, which is located on chromosome 18p11.31 and codes for the phosphatidic acid phosphatase LIPIN2. Data to date indicate that a disruption of phosphatidic acid phosphatase activity in LIPIN2 leads to immune system dysregulation due to abnormal activation of the NLRP3 inflammasome and overproduction of proinflammatory cytokines, including IL-1beta.

Clinical featuresThis section has been translated automatically.

Early onset with 1 to 3 inflammatory, sometimes febrile episodes per month . Further failure to thrive, height and weight were below the 5th percentile in the first-described family, and bone age was delayed. All affected individuals had significant hepatosplenomegaly. Blood transfusions were required on several occasions. Inconstant occurrence of Sweet syndrome as well as severe pustular psoriasis (Ferguson et al. 2005). The clinical course in the first-described family was similar in all 3 children; the unaffected parents in both families were related by blood.

LaboratoryThis section has been translated automatically.

Signs of inflammation; in peripheral blood smears: frequent hypochromia and microcytosis.

TherapyThis section has been translated automatically.

There is evidence that pharmacologic blockade of the interleukin-1 pathway is associated with rapid clinical improvement (Ferguson PJ et al. 2021).
