Popis: | Action myoclonus-renal failure syndrome (AMRF) is considered a rare form of progressive myoclonus epilepsy (PME) associated with renal failure. A mutation on the gene encoding the lysosomal integral membrane protein type 2-LIMP-2 (SCARB2), the receptor responsible for targeting glucocerebrosidase to the lysosomes, was recently described, allowing a better understanding of its etiopathogenesis.We describe clinically two sisters with AMRF that resulted from a mutation in the SCARB2 gene. The renal involvement was due to nephropathy C1q. When substrate-reduction therapy, to correct the possible glucocerebroside storage in the cells with glucocerebrosidase deficiency, was administered to one of the siblings, a significant improvement was observed. This report points out a rational for a therapeutical approach to this new lysossomopathy. |
