RBP2
rbp2 Gene: Decoding the Molecular Orchestrator of Hematopoiesis
Description
The rbp2 gene, formally known as the retinoblastoma protein 2 gene, plays a pivotal role in regulating the development and differentiation of blood cells, a process known as hematopoiesis. Located on chromosome 6p22.3, this gene encodes the RBP2 protein, a master regulator of gene expression that controls the balance between cell proliferation, differentiation, and apoptosis.
Associated Diseases
Mutations in the rbp2 gene have been implicated in a spectrum of hematological disorders. The most common and well-studied disease associated with rbp2 mutations is juvenile myelomonocytic leukemia (JMML), a rare but aggressive childhood cancer characterized by overproduction of immature blood cells. Other rare disorders linked to rbp2 mutations include:
- Congenital neutropenia
- Thrombocytopenia (low platelet count)
- Refractory anemia
- Myelodysplastic syndrome
Did you Know ?
Approximately 25-35% of JMML cases are caused by mutations in the rbp2 gene. These mutations often occur in specific "hotspots" within the gene, particularly in exon 1.
