Spinal Muscular Atrophy, Jokela Type; Smaj

Description

The Jokela type of spinal muscular atrophy (SMAJ) is an autosomal dominant lower motor neuron disorder characterized by adult-onset of muscle cramps and fasciculations affecting the proximal and distal muscles of the upper and lower limbs. The disorder is slowly progressive, resulting in weakness and mild muscle atrophy later in life (summary by Jokela et al., 2011).
