Specific granule deficiency 2

Summary

Specific granule deficiency-2 (SGD2) is an autosomal recessive immunologic disorder characterized by recurrent infections due to defective neutrophil development. Bone marrow findings include paucity of neutrophil granulocytes, absence of granule proteins in neutrophils, abnormal megakaryocytes, and features of progressive myelofibrosis with blasts. The disorder is apparent from infancy, and patients may die in early childhood unless they undergo hematopoietic stem cell transplantation. Most patients have additional findings, including delayed development, mild dysmorphic features, tooth abnormalities, and distal skeletal defects (Witzel et al., 2017). For a discussion of genetic heterogeneity of SGD, see SGD1 (245480). [from OMIM]
