What is the official name of the COCH gene?
The official name of this gene is “cochlin.”
COCH is the gene's official symbol. The COCH gene is also known by other names, listed below.

What is the normal function of the COCH gene?
The COCH gene provides instructions for making a protein called cochlin. This protein is abundant in certain parts of the inner ear called the cochlea and the vestibular system. The cochlea is a snail-shaped structure that helps process sound, and the vestibular system consists of fluid-filled canals that help maintain the body's balance and orientation in space. Cochlin is exported from cells in the cochlea and vestibular system and becomes part of the extracellular matrix. The extracellular matrix is an intricate lattice that forms in the space between cells and provides structural support. Two regions of the cochlin protein, called the LCCL and vWFA domains, probably coordinate cochlin's interactions with other molecules in the extracellular matrix. These interactions are important in forming the extracellular matrix and keeping it organized. Although the exact role of cochlin remains unknown, it likely plays a role in the structure of the inner ear.
