General Discussion

Mucolipidosis IV is a rare metabolic disorder characterized by intellectual disability; severe impairment in the acquisition of skills requiring the coordination of muscular and mental activities (psychomotor retardation); diminished muscle tone (hypotonia); clouding (opacity) of the clear portion of the eyes through which light passes (cornea); and progressive degeneration of the nerve-rich membrane lining the eyes (retinal degeneration). Mucolipidosis IV is inherited as an autosomal recessive genetic trait and caused by mutations in the MCOLN1 gene.
