Genetic Manipulation and Hybridization Update

Blog note: As in the days of Noah. All flesh was corrupted. Only Noah was perfect in his generation (not genetic corruption). End of note.

How is a baby’s genome sequenced?

“The first genome was sequenced in 2003 and cost $3 billion to do,” Lantos recalled. Today, sequencing is “a combination of computer applications and people,” he explained.

First, a genome machine “spits out” the millions of base pairs of an individual genome, said Lantos. Next, a computer program sifts through these pairs and boils them down to a subset. This “preliminary cut” might show a 100 genetic mutations that appear to be disease-causing, 19,000 that look harmless and 1,000 mutatations of unknown significance, he said.

For the last step in the process, a trained genetic scientist looks at that result and does an analysis “that is more art than science,” said Lantos.

It’s only become technically feasible to do full-scale sequencing studies, including the several infant studies sponsored by the NIH, in the last five years, he said: “The question is, can we develop a way to use this innovation that does more good than harm?”
