New Study Shows Each Person has "At Least 100 Mutations"

Every person born has at least 100 new mutations in her genome, and probably a lot more. That was the finding from a group of scientists who studied genetic mutations in two men from an extended family. The scientists published their work in Current Biology, and described using rapid DNA sequencing technology to investigate the subtle genetic differences that signal mutation from one generation to the next. Based on the number of mutations they found, the scientists estimate most people would have between 100-200 unique mutations in their genomes.
