Mucolipidosis type IV |

| Synonyms |
MLIV |
|
| Definitions |
(MLIV) - Autosomal recessive lysosomal storage disorder characterized by severe psychomotor retardation and ophthalmologic abnormalities, including corneal opacity, retinal degeneration and strabismus. Storage bodies of lipids and water-soluble substances are seen by electron microscopy in almost every cell type of the patients. Most patients are unable to speak or walk independently and reach a maximal developmental level of 1-2 years. All patients have constitutive achlorhydia associated with a secondary elevation of serum gastrin levels. MLIV may be due to a defect in sorting and|or transport along the late endocytic pathway. MLIV is found at relatively high frequency among Ashkenazi Jews. |
