Myoclonus-nephropathy syndrome is an autosomal recessive disorder caused by mutations of the SCARB2 gene. Neurological and nephrological symptoms may be isolated. The neurology includes progressive myoclonic epilepsy. The nephrological pathology is characterized by prorgressive glomerular nephropathy with sometimes nephrotic range proteinuria. Histomorphology includes collapsing glomerulopathy and glomerulosclerosis. Manifestation is in young adults.
The action myoclonus–renal failure syndrome was first described in a poster abstract in 1981 and then published 1986 by the same author, Andermann E.[Error: Macro 'ref' doesn't exist]
