Late-onset spinal motor neuronopathy

Late-onset spinal motor neuronopathy, LOSMoN, is an adult-onset autosomal dominant lower motor neuron disorder identified first in Finland. LOSMoN is primarily caused by the c.197G>T p.G66V mutation in the gene CHCHD10, represented by rs730880031. The clinical phenotype of LOSMoN is clarified in a doctoral thesis published in December 2015, "Late-onset spinal motor neuronopathy- a new neuromuscular disease".
