Abstract Pure hereditary spastic paraparesis (HSP) is an upper motor neuron syndrome clinically characterized by slowly progressive weakness and spasticity of the legs. To determine the chromosomal location of the genetic defect, a five-generational Dutch family with autosomal dominant pure HSP was subjected to linkage studies. Analysis was carried out on 48 members spanning three generations, of whom 23 individuals are definitely affected. By screening the genome with a total of 167 microsatellite markers distributed over all autosomes, an exclusion map for HSP was constructed. Depending on the actual size of the human genome, our exclusion map covered between 40% and 65% of its autosomal length. Loci on chromosomes 1, 8, 13, 14, and 18 showed slightly positive lod scores. The areas around these loci were investigated more closely, but no conclusive evidence for, or against, linkage could be obtained.
