Abstract:
A primary genetic linkage map for human chromosome 15 has been constructed from 16 arbitrary DNA markers genotyped in 59 large reference families. The map spans a genetic distance of 146 cM in males and 187 cM in females. The ratio of female/male genetic distance was approximately 2.1 overall within the region of the chromosome covered by our map, but three segments showed a significant male excess in recombination frequency. A subset of seven of the linked markers would be enough to detect linkage of a genetic defect within the mapped region of chromosome 15, if at least 48 phase-known meioses in affected families were available for analysis.
