Molecular diagnosis of childhood proximal spinal muscular atrophy has been enhanced by the discovery of the survival motor neuron (SMN) gene, which is absent or truncated in 98.6% of patients. To determine whether deletion analysis of the SMN gene may also be diagnostic for adult-onset disease, we studied six patients and found deletions in all. This finding will facilitate the diagnosis of adult-onset spinal muscular atrophy, and provides evidence for genetic homogeneity between the clinically diverse adult and childhood forms of the disease.
