God’s Red Pencil? CRISPR and The Three Myths of Precise Genome Editing

Published today in Independent Science News, “God’s Red Pencil? CRISPR and The Three Myths of Precise Genome Editing” was written by Jonathan Latham, PhD.

crispr-cas9-300x166Synopsis:  According to the media, “genome editing” techniques can precisely alter the DNA of living organisms. Furthermore, these new genetic engineering techniques are so “red-hot” and “game-changing” they will transform the landscapes of medicine and agriculture. Their safety and effectiveness hinges crucially on the claim of precision, yet how plausible is it? This article delineates three ways in which these technologies currently lack precision. 1) Present versions of CRISPR and other technologies are error prone and unpredictable. 2) Even if they were precise, purposeful manipulation of DNA depends on understanding of its functions, which we largely lack 3) CRISPR boosters are proceeding on a commonplace but faulty premise of gene function that is not supported by science. They have a dangerously narrow vision of how DNA influences traits that frames risk assessment as unnecessary.
