Agammaglobulinemia 9, autosomal recessive(AGM9)

MedGen UID:
1794269
Concept ID:
C5562059
Disease or Syndrome
Synonyms: AGAMMAGLOBULINEMIA, AUTOSOMAL RECESSIVE, DUE TO SLC39A7 DEFECT; AGM9
 
Gene (location): SLC39A7 (6p21.32)
 
Monarch Initiative: MONDO:0030519
OMIM®: 619693

Definition

Agammaglobulinemia-9 (AGM9) is an autosomal recessive primary immunodeficiency characterized by recurrent bacterial infections associated with agammaglobulinemia and absence of circulating B cells. Additional features include failure to thrive and skin involvement. The severity is variable: more severe cases may require hematopoietic stem cell transplantation, whereas others can be treated effectively with Ig replacement therapy (summary by Anzilotti et al., 2019). For a discussion of genetic heterogeneity of autosomal agammaglobulinemia, see AGM1 (601495). [from OMIM]
