However, the fibromyalgia GWAS study* used a technique that tied other variants associated with fibromyalgia to the central nervous system - eQTL (expression Quantitative Trait Locus) analysis.
To be fair, this seems less prone to bias than simply designating certain genes to be 'brain genes' since they are associated with 'brain diseases'.
I'm still skeptical, given my own experience with fibromyalgia - though it is possible that I don't actually have fibromyalgia, but instead have an autoinflammatory condition that is driven by NLRP3 inflammasome activation caused by being a familial Mediterranean fever gene (mutant MEFV) carrier.
On the other hand, my symptoms closely match those of fibromyalgia, and I see myself in fibromyalgia patient stories. I have allergies, eczema, and asthma - which are common comorbidities**. And like many people with fibromyalgia, I have found symptom relief through the elimination of dietary triggers*** and treatments that target the immune system.

-------------------------------------------------TITLE: Why do some children develop ADHD after stressful events while others do not?
Children exposed to stressful life events may face a greater risk of developing ADHD symptoms, but a new study suggests that vulnerability depends partly on family mental health, genetic risk, and brain development. These findings were published in the Journal of Child Psychology and Psychiatry.
ADHD is commonly associated with difficulties involving attention, impulsive behavior, and activity levels. Researchers have long known that both inherited factors and environmental experiences contribute to ADHD. Stressful events during childhood, including violence, serious accidents, or other major disruptions, may interfere with emotional development and brain systems involved in attention and self-control.
Yet exposure to stress is not a straightforward explanation for ADHD. Some children show substantial difficulties after stressful experiences, while others appear relatively resilient. The new study aimed to identify the factors that might explain these differences.
Led by Seung Yun Choi of Seoul National University, the research team examined data from the Adolescent Brain Cognitive Development study. The initial group included 6,303 children, 46.8 percent of whom were female, aged approximately 9.9 years at the beginning of the study. The children were assessed again after one year and two years.
The researchers considered several types of information, including ADHD symptoms, stressful life events, parental mental health difficulties, genetic measures, and connections between brain regions. Choi and colleagues then utilized a machine-learning approach, an advanced form of data analysis, to examine the complex relationships between these factors.
The results revealed that stressful experiences were associated with increased ADHD symptoms at both follow-up points. However, the size of this association varied considerably between children. At the one-year follow-up, children considered most vulnerable had higher levels of parental depression and parental ADHD. They also differed from lower-risk children on a genetic measure related to smoking behavior.
By the two-year follow-up, parental mental health problems remained important, and a higher genetic risk score for ADHD also became a significant factor. The researchers also identified differences in the physical connections between parts of the brain involved in planning, attention, and behavioral control.
The contrast between the groups was substantial. At one year, the estimated effect of stressful events was more than twice as large in the highest-risk group as in the lowest-risk group. A similar pattern was observed after two years.
The authors emphasized that their findings “underscore the importance of integrating environmental, genetic, and neural variables to identify children vulnerable or resilient to developing ADHD symptoms following early-life stress.”
The findings do not mean that genes determine whether a child will develop ADHD, nor that family mental health difficulties inevitably lead to symptoms. Instead, they suggest that children may differ in how strongly they respond to stressful environments. Family support, early assistance, and treatment for parental mental health problems could therefore be important parts of prevention.
The study has several limitations. For instance, the definition of stressful life events the authors utilized is based on the level of exposure, which may not adequately capture the subjective intensity of these experiences.
The study, “Individual differences in effects of stressful life events on childhood ADHD: genetic, neural, and familial contributions,” was authored by Seung Yun Choi, Jinwoo Lee, Junghoon Park, Eunji Lee, Bo-Gyeom Kim, Gakyung Kim, Yoonjung Yoonie Joo, and Jiook Cha.

#AcademiaHive mind: we're revamping a journal club course that has used the same stack of papers for a very long time. I have some favorites I'm listing as candidates.
If you have suggestions for papers, fire 'em at me. It's second year grad students with focuses in molecular genetics and genomics. Anything spanning across genetics, genomics, and computational biology are contenders.
Looking for neat concepts, designs, cool findings, etc etc to dissect

Not every DNA mistake gets fixed. We know that; that's how mutations enter the gene pool. But it gets more interesting to look at what does get fixed, because repair enzymes apparently have a priority list.

🧬 Everyone alive today carries DNA from a mysterious "ghost" ancestor — an unknown archaic human species that no fossil record has ever captured.
Using a new method called TRACE, scientists analyzed 503 modern genomes and found that 0.5-1% of our DNA comes from an unidentified hominin lineage that split from us over 800,000 years ago.
This ghost lineage interbred with early Homo sapiens in Africa before the out-of-Africa migration. Unlike Neanderthal and Denisovan DNA, which is mostly absent from speech-related gene regions, the ghost DNA appears even in those areas.
The discovery also revealed an even older "super-archaic" lineage — one that branched off nearly 1.8 million years ago and reached us indirectly through Denisovans.
We carry the genetic legacy of ancestors we never knew existed.

You can't buy a hypoallergenic dog — yet. But the arrival of Bailey and Alfie may herald a new era for sniffly canine fans. Kindred Companion Sciences used DNA-altering CRISPR technology to knock out Can f 1, the major allergy-causing protein in dogs' DNA, when breeding the two beagles. They were born in September 2024 and developed as normal — minus the problematic protein. Here's more from The Week.
