Spinal muscular atrophy with progressive myoclonic epilepsy
Hereditary myoclonus-progressive distal muscular atrophy syndrome
This condition is inherited in an autosomal recessive manner
Classification and external resources
ICD- 10 G25.3
Spinal muscular atrophy with progressive myoclonic epilepsy ( SMA-PME), sometimes called Jankovic–Rivera syndrome, is a very rare neurodegenerative disease whose symptoms include slowly progressive muscle wasting ( atrophy), predominantly affecting distal muscles, combined with denervation and myoclonic seizures. 
SMA-PME is associated with a
missense mutation (c.125C→T) or deletion in exon 2 of the ASAH1 gene and is inherited in an autosomal recessive manner. As with many  genetic disorders, there is no known cure to SMA-PME.
The condition was first described in 1979 by American researchers
Joseph Jankovic and Victor M. Rivera.
