Heritability and biological consequences of human variation in mitotic recombination [ 2001 - 2002 ]

Research Grant

Researchers: David Turner (Principal investigator)

Brief description Cells in our bodies constantly sustain damage to their genetic material (genes) most of which is efficiently repaired. Some is not and accumulated damage to genes in a cell can start a cancer. There are several repair mechanisms that cells possess which have evolved since the earliest life-forms. One repair mechanism homologous recombination repair will, as a minor by-product of its activity, produce an event called mitotic recombination (MR). MR causes a loss of diversity of genes and this can contribute to cancer rather than prevent it. We have shown that the rate at which MR occurs varies very widely in humans. In this project we will devise a simple method for measuring MR, use identical and non identical twins to find if the rate of MR is inherited and finally see whether the rate of MR is associated with risk of cancer, as we expect.
