Eight chromosome 6p markers (MUT, D6S4, D6S5, D6S19, D6S29, PIM, HLA, and F13A) were regionally mapped using somatic cell hybrid deletion cell lines that retained different regions of chromosome 6p. New restriction fragment length polymorphisms were identified at the D6S5 and PIM loci using newly isolated genomic clones at these loci. Genetic linkage among the eight loci was determined using the 40 CEPH reference families. Linkage analyses showed that these loci are in one linkage group spanning 48 cM in males and 128 cM in females. Using both the deletion mapping data and multipoint linkage analyses, chromosomal order for these loci was determined as centromere-(MUT, D6S4)-(D6S5, D6S19)-(D6S29, PIM)-HLA-F13-A-telomere. Analyses of sex-specific recombination frequencies revealed a higher rate of recombination in females in the region between D6S4 and D6S29, while the recombination rate in males was higher for the interval between D6S29 and the HLA loci.
