CYP Testing to Help Prevent Dangerous Adverse Drug Reactions

Drug-drug interactions can be extremely dangerous, even if the CYPs are genetically normal. The picture becomes even more grim if we take into account drug-gene interactions. Genetic testing for variants in the CYP enzyme system will definitely save lives.

Schizophrenia Twin Research as Reported in The Gene: An Intimate History...

21
In his 2016 book The Gene: An Intimate History, cancer physician and researcher Siddhartha Mukherjee chronicled the initial idea of the gene, taking readers through the history of genetics up to the current “post-genome” period by interweaving science, social history, and his own personal narrative. In the process he documented some of the crimes of the eugenics movement and the monstrous atrocities committed by German National Socialism in the name of eugenics and biology, while noting the Nazi’s promotion of twin research. He also criticized aspects of intelligence testing and genetic theories of racial inferiority based on IQ tests. At the same time, Mukherjee supported and promoted many contemporary behavioral genetics positions.

Schizophrenia and Genetics: A Closer Look at the Evidence
