>From The New York Times article:
"Besides identifying disease genes, one team, in Seattle, was able to make
the first direct estimate of the number of mutations, or changes in DNA,
that are passed on from parent to child. They calculate that of the three
billion units in the human genome, 60 per generation are changed by random
mutation — considerably less than previously thought."
"[C]ommon diseases, surprisingly, are caused by rare, not common, mutations.
In the last few months, researchers have begun to conclude that a new
approach is needed, one based on decoding the entire genome of patients."
"The Seattle team believes whole-genome sequencing can be applied to the
study of the common multigene diseases and plans to sequence more than 100
genomes next year, starting with multigenerational families."
Complete Genomics of Mountain View, Calif., has developed a new DNA
sequencing method. Clifford Reid, the chief executive, "said that the
company was scaling up to sequence 500 genomes a month and that for large
projects the price per genome would soon drop below $10,000. 'We are on our
way to the $5,000 genome,' he said."
