- Tissue and cell-type dependent impact of secondary glucocerebrosidase abnormalities due to LIMP-2 deficiencyPublication . Gaspar, Paulo; Kallemeijn, Wouter; Strijland, Anneke; Van Eijk, Marco; Van Roomen, Cindy; Ottenhoff, Roloef; Mirzaian, Mina; Ferraz, Maria; Donker-Koopman, Wilma; Macario, Maria do Carmo; Saftig, Paul; Overkleeft, Herman; Sá Miranda, Clara; Aerts, HansSphingolipidoses comprise the most prevalent group of lysosomal storage disorders. The most frequent is Gaucher disease (GD), where it occurs the storage of the glycosphingolipid glucosylceramide (GlcCer) due to a deficiency in the enzyme glucocerebrosidase (GCase). GD is a multi-systemic disorder affecting most organs, resulting in cytopenia, hepatosplenomegaly and skeletal abnormalities. Only recently, lysosomal integral membrane protein, type 2 (LIMP-2) has been identified as the receptor involved in the intracellular sorting and trafficking of the enzyme GCase to lysosomes. Deficiency of LIMP-2 causes Action Myoclonic-Renal Failure (AMRF), which clinically differs from GD. AMRF patients present renal dysfunction and failure, myoclonic epilepsy and ataxia with progressive neurological impairment .
