Beschreibung:
The genome-wide recombination rate varies between individuals, but the mechanism controlling this variation in humans has remained elusive. A genome-wide search identified sequence variants in the 4p16.3 region correlated with recombination rate in both males and females. These variants are located in the RNF212 gene, a putative ortholog of the ZHP-3 gene that is essential for recombinations and chiasma formation in Caenorhabditis elegans. It is noteworthy that the haplotype formed by two single-nucleotide polymorphisms (SNPs) associated with the highest recombination rate in males is associated with a low recombination rate in females. Consequently, if the frequency of the haplotype changes, the average recombination rate will increase for one sex and decrease for the other, but the sex-averaged recombination rate of the population can stay relatively constant.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kong, Augustine -- Thorleifsson, Gudmar -- Stefansson, Hreinn -- Masson, Gisli -- Helgason, Agnar -- Gudbjartsson, Daniel F -- Jonsdottir, Gudrun M -- Gudjonsson, Sigurjon A -- Sverrisson, Sverrir -- Thorlacius, Theodora -- Jonasdottir, Aslaug -- Hardarson, Gudmundur A -- Palsson, Stefan T -- Frigge, Michael L -- Gulcher, Jeffrey R -- Thorsteinsdottir, Unnur -- Stefansson, Kari -- New York, N.Y. -- Science. 2008 Mar 7;319(5868):1398-401. doi: 10.1126/science.1152422.
