Mosaic genomes could complicate genetic screening

x

The idea that every cell in our body contains identical DNA is incorrect, with scientists discovering that genetic variations are widespread throughout the body’s tissues. The findings, say the researchers, have profound implications for genetic screening as they directly challenge the longstanding belief that the cells which govern our body’s functions have the same DNA sequence. A paper detailing the new research by scientists from Yale and Stanford appears in the journal Nature.
