The 10 pages that link to Spinal muscular atrophy, each with the reason it gives.

• Newborn screeningBroader topic: Screening can identify affected infants before symptoms, when early treatment may improve outcomes.

• Motor neuronRelated: Its muscle weakness follows loss of spinal motor neurons.

• Alternative splicingRelated: Its treatment can alter SMN2 splicing to increase production of functional protein.

• Muscular dystrophyCompared with: It can resemble muscular dystrophy clinically, but its primary defect lies in motor neurons.

• RNA splicingRelated: A disease-causing difference in SMN2 splicing makes exon inclusion a therapeutic target.

• HypotoniaRelated: It can present with hypotonia and weakness from loss of lower motor neurons.

• Lower motor neuronBroader topic: It is a disease centered on loss of spinal lower motor neurons.

• Congenital myopathyCompared with: It can resemble congenital myopathy but primarily damages motor neurons rather than muscle fibers.

• Becker muscular dystrophyCompared with: It can cause weakness but originates in motor neurons rather than dystrophin-deficient muscle fibers.

• ArthrogryposisCompared with: It can cause severe weakness, but its defining process is progressive motor-neuron loss rather than congenital joint contractures.
