A High-Resolution Linkage Map of Human 9q34.1

A map comprising 16 distinct markers with heterozygosities of 0.61-0.92 for a 10-cM region of human 9q34.1 is presented. The map incorporates four genes and has a maximum intermarker interval of 2.1 cM. Markers were analyzed in the Venezuelan reference pedigrees and all were placed uniquely in the map with a minimum likelihood of 676:1. The map should prove useful in analysis of families segregating dystonia and tuberous sclerosis, as the DYT1 and TSC1 loci map within this region.
