Summaries for Specific Granule Deficiency 2

OMIM : 57 Specific granule deficiency-2 is an autosomal recessive immunologic disorder characterized by recurrent infections due to defective neutrophil development. Bone marrow findings include hypercellularity, abnormal megakaryocytes, and features of progressive myelofibrosis with blasts. The disorder is apparent from infancy, and most patients die in early childhood unless they undergo hematopoietic stem cell transplantation. Some patients may have additional findings, including delayed development, mild dysmorphic features, and distal skeletal anomalies (summary by Witzel et al., 2017). For a discussion of genetic heterogeneity of SGD, see SGD1 (245480). (617475)

MalaCards based summary : Specific Granule Deficiency 2, is also known as sgd2. An important gene associated with Specific Granule Deficiency 2 is SMARCD2 (SWI/SNF Related, Matrix Associated, Actin Dependent Regulator Of Chromatin, Subfamily D, Member 2). Affiliated tissues include bone, neutrophil and bone marrow, and related phenotypes are anemia and myelodysplasia

UniProtKB/Swiss-Prot : 75 Specific granule deficiency 2: A form of specific granule deficiency, an autosomal recessive disorder characterized by recurrent pyogenic infections, defective neutrophil chemotaxis and bactericidal activity, and lack of neutrophil secondary granule proteins. SGD2 is due to defective neutrophil development. Bone marrow findings include hypercellularity, abnormal megakaryocytes, and features of progressive myelofibrosis with blasts. Some patients may have additional findings, including delayed development, mild dysmorphic features, and distal skeletal anomalies.
