Membrane protein MLC1 is a protein that in humans is encoded by the MLC1 gene.
MLC1 (also called WKL1) is the only human gene currently associated with megalencephalic leukoencephalopathy with subcortical cysts (MLC). Evidence exists for at least one other gene for MLC, but it has not been mapped or identified.
The function of this gene product is unknown; however, homology to other proteins suggests that it may be an integral membrane transport protein. Mutations in this gene have been associated with megalencephalic leukoencephalopathy with subcortical cysts, an autosomal recessive neurological disorder.
