Genetic counseling should be offered to all families of patients with spinal muscular atrophy. Obtaining a complete family history facilitates genetic counseling. Carrier testing is available for commercial use. A recent study of 68,471 individuals showed that carrier-status testing may be feasible given the high carrier prevalence (1 in 54 overall). [61]

Education on how the disease is inherited may avert conception of affected individuals.

Furthermore, the role of prenatal diagnosis, particularly in pregnant carriers or those with juvenile or adult-onset forms, should also be addressed.
