What is GATA2 mutation?
What is GATA2 mutation?
GATA2 deficiency is caused by germline mutations in the GATA2 gene. Germline means that the mutation is present in every cell in the body, not just the immune system cells. The GATA2 gene produces a protein called a transcription factor. Transcription factors regulate when other genes are turned on.
Can GATA2 deficiency be cured?
To date, allogeneic bone marrow transplantation (BMT) is the only potentially curative treatment for GATA2 deficiency.
What is RUNX1 mutation?
RUNX1 is a recurrently mutated gene in sporadic myelodysplastic syndrome and leukemia. Inherited mutations in RUNX1 cause familial platelet disorder with predisposition to acute myeloid leukemia (FPD/AML). In sporadic AML, mutations in RUNX1 are usually secondary events, whereas in FPD/AML they are initiating events.
What does GATA2 stand for?
GATA2 or GATA-binding factor 2 is a transcription factor, i.e. a nuclear protein which regulates the expression of genes. It regulates many genes that are critical for the embryonic development, self-renewal, maintenance, and functionality of blood-forming, lympathic system-forming, and other tissue-forming stem cells.
What is GATA3?
The GATA3 transcription factor is critical for the embryonic development of various tissues as well as for inflammatory and humoral immune responses and the proper functioning of the endothelium of blood vessels. GATA3 plays central role in allergy and immunity against worm infections.
What is ASXL1 mutation?
ASXL1 mutations are frameshift and nonsense mutations that are supposed to result in C-terminal truncation of the protein upstream of the PHD finger (Figure 1). The functional relevance of some reported missense mutations is not clear.
What does RUNX1 gene do?
RUNX1 is a transcription factor that forms a complex with the cofactor CBFB. This complex provides stability to the RUNX1 protein which is involved in the generation of hematopoietic stem cells and for their differentiation into myeloid and lymphoid lines.
What does positive for GATA3 mean?
A recent study found GATA-3 to be associated with favorable breast cancer pathologic features, including negative lymph node and positive estrogen receptor (ER) status. GATA-3 levels were also found to be an independent prognostic marker, with low expression predicting for breast cancer recurrence.
What does ASXL1 stand for?
ASXL1 (ASXL Transcriptional Regulator 1) is a Protein Coding gene. Diseases associated with ASXL1 include Bohring-Opitz Syndrome and Myelodysplastic Syndrome.
Where is RUNX1 located?
chromosome 21
Gene and protein In humans, the gene RUNX1 is 260 kilobases (kb) in length, and is located on chromosome 21 (21q22. 12). The gene can be transcribed from 2 alternative promoters, promoter 1 (distal) or promoter 2 (proximal).
What happens to a person with GATA2 deficiency?
GATA2 deficiency is caused by a variety of mutations in the GATA2gene and can have variable presentation, onset and outcome. Patients are susceptible to mycobacterial, viral and fungal infections and can develop MDS, acute or chronic leukemias, lymphedema and pulmonary alveolar proteinosis.
What are the mutations in the GATA2 gene?
GATA2 gene mutations. Inactivating mutations in the GATA2 gene are the primary cause of GATA2 deficiency disorders. This gene is a member of the evolutionarily conserved GATA transcription factor gene family. All vertebrate species tested so far, including humans and mice, express 6 GATA genes, GATA1 through GATA6.
How are GATA2 deficiency and myelodys plastic syndrome related?
– acterized by immunodeficiency, myelodys- plastic syndrome (a condition characterized by ineffective blood cell production), lung dis- ease, and problems of the vascular/lymphatic system. GATA2 deficiency is diagnosed based on clinical findings, laboratory tests, and genetic testing.
What is the role of GATA2 in hematopoiesis?
GATA2 is a zinc finger transcription factor essential for embryonic and definitive hematopoiesis as well as lymphatic angiogenesis. GATA2 deficiency is caused by a variety of mutations in the GATA2gene and can have variable presentation, onset and outcome.
