Family genetic research reveals the speed of human mutation
Date:6/12/2011

etween families. "We saw that the number of mutations from the male was less than the number of mutations from the female in one of the families," Awadalla explained. "This doesn't mean that we're throwing the theory out the window, it simply means that the mutation rate is extremely variable from individual to individual, or even that some people have mechanisms that reduce the likelihood of mutations." He also noted that this finding would have important implications for research that attempts to tie specific genetic mutations to diseases.

Researchers will need to undertake further studies with more families to better understand just how variable the individual mutation rate is. "We also need to be looking at other kinds of mutations, such as structural variations within our genetic code," Awadalla said.
