Spinal muscular atrophy is one of the most common severe inherited diseases in childhood and especially the acute form of type I (Werdnig-Hoffmann) results in early death. Recently, all three types of childhood-onset SMA have been mapped to chromosome 5. Since then heterozygote detection in siblings and prenatal diagnosis of SMA type I is possible by indirect genetic analysis. As the gene and the mutation responsible for the disease have not yet been cloned, DNA analysis results in a risk figure which depends on the informativity and recombination frequency of the flanking markers studied.
