| Abstract: | A genetic linkage map of markers for the short arm of human chromosome 8 has been constructed with 14 polymorphic DNA markers on the basis of genotypes obtained in 40 CEPH reference families. This unbroken map spans 45 cM in males and 79 cM in females. The 14 markers include three genes, MSR, LPL, and NEFL, and one anonymous DNA segment that were previously assigned to chromosome 8. The other 10 marker had been isolated from a chromosome 8-specific cosmid library and physically localized to chromosomal bands by fluorescence in situ hybridization. The order of loci determined by genetic linkage was consistent with their physical locations. This map will facilitate efficient linkage studies of human genetic diseases that may be segregating on chromosome 8p and will provide anchor points for development of high-resolution maps for this chromosomal region. |
