What is the official name of the FLT4 gene?
The official name of this gene is “fms-related tyrosine kinase 4.”
FLT4 is the gene's official symbol. The FLT4 gene is also known by other names, listed below.

What is the normal function of the FLT4 gene?
The FLT4 gene provides instructions for making a protein called vascular endothelial growth factor receptor 3 (VEGFR-3), which regulates the development and maintenance of the lymphatic system. The lymphatic system produces and transports fluids and immune cells throughout the body. VEGFR-3 is turned on (activated) by two proteins called vascular endothelial growth factor C (VEGF-C) and vascular endothelial growth factor D (VEGF-D). When VEGF-C and VEGF-D attach (bind) to VEGFR-3, chemical signals are produced that regulate the growth, movement, and survival of lymphatic cells.
Does the FLT4 gene share characteristics with other genes?
The FLT4 gene belongs to a family of genes called immunoglobulin superfamily, immunoglobulin-like domain containing (immunoglobulin superfamily, immunoglobulin-like domain containing). It also belongs to a family of genes called immunoglobulin superfamily, I-set domain containing (immunoglobulin superfamily, I-set 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.
