Green List (high evidence)

This primary immunodeficiency, designated IMD21, DCML, or MONOMAC, is characterized by profoundly decreased or absent monocytes, B lymphocytes, natural killer (NK) lymphocytes, and circulating and tissue dendritic cells (DCs), with little or no effect on T-cell numbers. Clinical features of IMD21 are variable and include susceptibility to disseminated nontuberculous mycobacterial infections, papillomavirus infections, opportunistic fungal infections, and pulmonary alveolar proteinosis.

Bone marrow hypocellularity and dysplasia of myeloid, erythroid, and megakaryocytic lineages are present in most individuals, as are karyotypic abnormalities, including monosomy 7 and trisomy 8. In the absence of cytogenetic abnormalities or overt dysplasia, hypoplastic bone marrow may initially be diagnosed as aplastic anaemia.

Less common manifestations of GATA2 deficiency include lymphoedema and sensorineural hearing loss, a phenotype usually termed 'Emberger syndrome'.

Over 20 unrelated individuals reported.
