OMIA 001691-9615 : Recombination rate in Canis lupus familiaris

In other species: Mallard , chicken , domestic cat , horse , pig , cattle , goat , sheep

Possibly relevant human trait(s) and/or gene(s) (MIM number): 612042 (trait)

Mendelian trait/disorder: yes

Considered a defect: no

Key variant known: no

Molecular basis: Axelsson et al. (2012) provided evidence that the canine lineage has lost the gene PRDM9, which in other lineages plays a central role in initiating recombination, creating recombination "hotspots". Lacking this gene, the canine lineage has a "greater evolutionary stability of recombination hotspots".

Campbell et al. (2016) concluded that despite lacking PRDM9, "dogs have similar broad scale properties of recombination to humans, while fine-scale recombination is similar to other species lacking PRDM9."
