NCIt definition : Human colony stimulating factor 1 receptor (CSF1R) gene, located at 5q33.2-q33.3,
encodes macrophage colony stimulating factor I receptor protein. Mutations in this
gene have been detected in both chronic myelomonocytic leukemia and type M4 acute
myeloblastic leukemia. One out of fifty hematologically normal individuals exhibit
a CSFR1 variant allele (Y969C) that may cause a predisposition to myeloid malignancy.;
