What is the official name of the FLI1 gene?
The official name of this gene is “Fli-1 proto-oncogene, ETS transcription factor.”
FLI1 is the gene's official symbol. The FLI1 gene is also known by other names, listed below.

What is the normal function of the FLI1 gene?
The FLI1 gene provides instructions for making the FLI protein, which controls the activity (transcription) of genes. Transcription is the first step in the process of producing proteins. The FLI protein is part of a group of related proteins, called the Ets family of transcription factors, that control transcription. The FLI protein attaches (binds) to certain regions of DNA and turns on (activates) the transcription of nearby genes. The proteins produced from these genes control many important cellular processes, such as cell growth and division (proliferation), maturation (differentiation), and survival. The FLI protein is found primarily in blood cells and is thought to regulate their development.
How are changes in the FLI1 gene related to health conditions?
Genetics Home Reference provides information about Jacobsen syndrome, which is also associated with changes in the FLI1 gene.
Where is the FLI1 gene located?
Cytogenetic Location: 11q24.1-q24.3
Molecular Location on chromosome 11: base pairs 128,686,535 to 128,813,267
(Homo sapiens Annotation Release 107, GRCh38.p2) (
The FLI1 gene is located on the long (q) arm of chromosome 11 between positions 24.1 and 24.3.
More precisely, the FLI1 gene is located from base pair 128,686,535 to base pair 128,813,267 on chromosome 11.
