Constitutive achlorhydria in mucolipidosis type IV.
Mucolipidosis type IV is an autosomal recessive lysosomal storage disease of unknown etiology that causes severe neurological and ophthalmological abnormalities. In an attempt to obtain insight into the nature of the metabolic abnormality in this disorder, we prospectively evaluated 15 consecutive patients, aged 2 to 23 years, over a period of 22 months. The finding of iron deficiency in some o...
متن کاملAutophagic dysfunction in mucolipidosis type IV patients
Mutations in Mucolipin 1 (MCOLN1) have been linked to mucolipidosis type IV (MLIV), a lysosomal storage disease characterized by several neurological and ophthalmological abnormalities. It has been proposed that MCOLN1 might regulate transport of membrane components in the late endosomal-lysosomal pathway; however, the mechanisms by which defects of MCOLN1 function result in mental and psychomo...
متن کاملMucolipidosis type IV and the mucolipins.
MLIV (mucolipidosis type IV) is a neurodegenerative lysosomal storage disorder caused by mutations in MCOLN1, a gene that encodes TRPML1 (mucolipin-1), a member of the TRPML (transient receptor potential mucolipin) cation channels. Two additional homologues are TRPML2 and TRPML3 comprising the TRPML subgroup in the TRP superfamily. The three proteins play apparently key roles along the endocyto...
متن کاملElectronegative electroretinogram in mucolipidosis IV.
OBJECTIVE To demonstrate the progression of electroretinographic (ERG) findings in mucolipidosis IV. METHODS Two patients with mucolipidosis IV were examined clinically and their condition was followed up for ophthalmic manifestations of the disease. Electroretinograms were performed on both patients, and conjunctival biopsy specimens were analyzed for characteristic ultrastructural inclusion...
متن کاملThe first genetically confirmed Japanese patient with mucolipidosis type IV
Mucolipidosis type IV (MLIV) is a rare neurodegenerative disorder characterized by severe psychomotor delay and visual impairment. We report the brain pathology in the first Japanese patient of MLIV with a novel homozygous missense mutation in MCOLN1. We detected the localized increase in p62-reactive astrocytes in the basal ganglia.
