Meiotic linkage mapping of 52 genes onto the canine map does not identify significant levels of microrearrangement

Meiotic linkage mapping of 52 genes onto the canine map does not identify significant levels of... In an effort to extend our understanding of the evolutionary relationship between the canine and human genomes, we have developed and positioned 52 new gene-associated polymorphic markers on the canine meiotic linkage map. Canine-specific PCR primers were developed from the consensus of published sequences of several mammalian genomes and were designed to span intronic regions, thus optimizing the probability that a polymorphic site was included. The resulting markers were analyzed on a panel of three-generation canine reference families and the data were incorporated into the current meiotic linkage map. The data were compared with those generated by three chromosome paint studies in an effort to understand the distribution and frequency of microrearrangements within the canine genome. Forty-eight of 52 genes map to a chromosomal region predicted to contain genes from the corresponding region of the human genome according to all published reciprocal chromosome paint studies. Meiotic linkage mapping data for three genes can be used to resolve discrepancies between the published reciprocal chromosome paint studies, and for an additional two genes, meiotic mapping data allow evolutionary breakpoints to be more precisely defined. We conclude that microrearrangements of evolutionarily conserved segments between the canine and human genomes are rare, occurring for less than 0.5% of gene data reported to date. In addition, we have found that the placement of genes on the meiotic linkage map is a useful mechanism for resolving discrepancies between existing data sets. Mammalian Genome Springer Journals
