The article explains how genetic differences influence brain structure, and how these structural variations relate to autism and attention disorders. It uses large genetic datasets to link specific brain regions and white matter pathways with the risk of these conditions, suggesting anatomy may precede symptom development.

This topic is of interest to psychology because it connects neural structure with behavioral outcomes, offering insight into how biology can shape cognitive and social functioning across development.

A recent MIT study demonstrates that different mutations within the MECP2 gene, which causes Rett syndrome, result in distinct neurological abnormalities and require targeted, mutation-specific treatments rather than a universal therapeutic approach.

Personalized Therapies for Rett Syndrome

MIT researchers used 3D brain organoids to show different MECP2 mutations in Rett syndrome require distinct, personalized therapeutic treatments.

Should you spend $1,000 to find out your "true" biological age? Researchers Idan Shalev and Abner Apsley write for @TheConversationUS about why DNA tests for epigenetic markers aren't useful at an individual level — but have enormous value when looking at populations.

Biological age tests reveal what slows or hastens aging – but they’re useful only for researchers, not consumers

Epigenetic aging clocks allow scientists to study how populations age. They aren’t intended for individuals to make health decisions.
