CSF3R (Colony Stimulating Factor 3 Receptor) is a protein-coding gene located on chromosome 1p34.3. The encoded protein, which belongs to the cytokine receptor family, may also play a role in some cell surface adhesion or recognition processes. Alternatively spliced transcript variants have been described.

DefinitionThis section has been translated automatically.
Clinical pictureThis section has been translated automatically.
Acquired activating heterozygous variants of CSF3R are the major cause of chronic neutrophilic leukemia, a hyperproliferative disease.
In contrast, biallelic hypomorphic germline variants of CSF3R are a rare cause of "severe congenital neutropenia (Kostmann syndrome)," a hypoproliferative disorder.
Versch. heterozygous CSF3R variants in the germline are risk factors for the development of myeloid and lymphoid malignancies. An important paralog of the CSF3R gene is IL6ST.
