What is the official name of the MLC1 gene?
The official name of this gene is “megalencephalic leukoencephalopathy with subcortical cysts 1.”
MLC1 is the gene's official symbol. The MLC1 gene is also known by other names, listed below.

What is the normal function of the MLC1 gene?
The MLC1 gene provides instructions for making a protein that is found in the brain, spleen, and white blood cells (leukocytes). Within the brain, the MLC1 protein is found in specialized cells called astroglial cells, which support and nourish other cells. Some researchers have suggested that astroglial cells play an important role in the functioning of oligodendrocytes, which are specialized cells that surround nerves and are involved in the production and long-term maintenance of myelin. Myelin forms a protective coating around certain nerve cells and ensures the smooth and rapid transmission of nerve impulses. The role of MLC1 protein in astroglial cells, the spleen, and leukocytes is unknown. Some research indicates that the MLC1 protein is involved in transporting molecules across the blood-brain barrier and the brain-cerebrospinal fluid barrier. These barriers protect the brain's delicate nerve tissue by allowing only certain substances to pass into the brain.
