Psychiatric genetics?

“The Dark Matter of Psychiatric Genetics”

by Carl Zimmer

Excerpt: “So it’s unlikely that doctors would actually run a brain mutation test on patients to search for this mosaicism. Instead, understanding the mosaic brain could offer a more general insight: by identifying the late-arising mutations that lead to mental disorders, scientists will better understand their biology. ”
My comment: With psychiatric genetics, Zimmer continues to take mutation-driven evolution to heightened levels of nonsensical misrepresentations. No experimental evidence suggests that mosaicism is associated with mutations. All experimental evidence shows that brain development is nutrient-dependent and pheromone-controlled. I think what we will continue to see from him are examples of  ‘Once a theorist, always a theorist” – type thinking, which is really not thinking at all about biological facts. See for example: Science Journalists: Neuronal copy number variation (CNV) revisited
