What is the official name of the FIG4 gene?
The official name of this gene is “FIG4 phosphoinositide 5-phosphatase.”
FIG4 is the gene's official symbol. The FIG4 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 FIG4 gene?
The FIG4 gene provides instructions for making a protein called Fig4, whose function is not well understood. Researchers believe that the Fig4 protein plays a role in regulating a compound called phosphatidylinositol-3,5-bisphosphate, or PtdIns(3,5)P(2). This compound is involved in the movement of small sac-like structures called vesicles that transport certain substances within cells (vesicle trafficking). The Fig4 protein also seems to help in the survival of nerve cells (neurons).
How are changes in the FIG4 gene related to health conditions?
Genetics Home Reference provides information about amyotrophic lateral sclerosis, which is also associated with changes in the FIG4 gene.
Where is the FIG4 gene located?
Cytogenetic Location: 6q21
Molecular Location on chromosome 6: base pairs 109,691,220 to 109,825,430
The FIG4 gene is located on the long (q) arm of chromosome 6 at position 21.
More precisely, the FIG4 gene is located from base pair 109,691,220 to base pair 109,825,430 on chromosome 6.
