What is the official name of the FLT3 gene?
The official name of this gene is “fms related tyrosine kinase 3.”
FLT3 is the gene's official symbol. The FLT3 gene is also known by other names, listed below.
Read more about gene names and symbols on the About page.
What is the normal function of the FLT3 gene?
The FLT3 gene provides instructions for making a protein called fms-like tyrosine kinase 3 (FLT3), which is part of a family of proteins called receptor tyrosine kinases (RTKs). Receptor tyrosine kinases transmit signals from the cell surface into the cell through a process called signal transduction. The FLT3 protein is found in the outer membrane of certain cell types where a specific protein called FLT3 ligand, or FL, can attach (bind) to it. This binding turns on (activates) the FLT3 protein, which subsequently activates a series of proteins inside the cell that are part of multiple signaling pathways. The signaling pathways stimulated by the FLT3 protein control many important cellular processes such as the growth and division (proliferation) and survival of cells, particularly of early blood cells called hematopoietic progenitor cells.
Does the FLT3 gene share characteristics with other genes?
The FLT3 gene belongs to a family of genes called CD (CD molecules). It also belongs to a family of genes called immunoglobulin superfamily, immunoglobulin-like domain containing (immunoglobulin superfamily, immunoglobulin-like domain containing).
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.
How are changes in the FLT3 gene related to health conditions?
Genetics Home Reference provides information about core binding factor acute myeloid leukemia, which is also associated with changes in the FLT3 gene.
Where is the FLT3 gene located?
Cytogenetic Location: 13q12
Molecular Location on chromosome 13: base pairs 28,003,274 to 28,100,592
(Homo sapiens Annotation Release 107, GRCh38.p2) (
The FLT3 gene is located on the long (q) arm of chromosome 13 at position 12.
More precisely, the FLT3 gene is located from base pair 28,003,274 to base pair 28,100,592 on chromosome 13.
