title: A primary genetic map of chromosome 13q.
abstract: We have constructed a primary genetic map spanning most of human chromosome 13. A total of 14 polymorphic DNA sequences and one protein polymorphism provided, after construction of haplotypes, seven markers for the long arm of this chromosome. A panel of cell lines from 30 three-generation families with large sibship size served as the sample set. Pairwise cross analysis of the inheritance patterns of the marker loci established that six of the seven loci constituted a single linkage group; the seventh was localized by physical means. Significantly higher recombination rates were found in female than in male meioses in several intervals. The six closely linked loci were arranged, based on the two-point data, in three clusters, and a number of alternate gene orders were excluded by three-point linkage tests. The order and spacing of the individual loci were refined by linkage analyses that considered five loci jointly.
