What is the official name of the FAT4 gene?
The official name of this gene is “FAT atypical cadherin 4.”
FAT4 is the gene's official symbol. The FAT4 gene is also known by other names, listed below.

What is the normal function of the FAT4 gene?
The FAT4 gene provides instructions for making a protein that is found in most tissues. The protein spans the membrane surrounding cells so that part of the protein is outside the cell and part of the protein is inside the cell. The precise function of the FAT4 protein is largely unknown; however, research shows that the FAT4 protein is likely involved in determining the position of various components within cells (cell polarity). The FAT4 protein is also thought to function as a tumor suppressor, which means that it keeps cells from growing and dividing too rapidly or in an uncontrolled way.
Does the FAT4 gene share characteristics with other genes?
The FAT4 gene belongs to a family of genes called CDH (cadherins).
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.
