Ready for a cram session? The discussion on Twitter this week was quite, well, studious, with deep dives into three studies and a philosophical discussion about language and thought.
Starting things off, Joon An, assistant professor of biosystem and biomedical science at Korea University in Seoul, tweeted about a study in which he and his colleagues generated whole-genome sequences from 242 Korean simplex families in order to better understand how de novo mutations (DNMs) affect chromatin interactions in people with autism.
His results indicated that “non-coding DNMs in ASD probands lead to early neurodevelopmental disruption implicated in ASD risk via chromatin interactions.”
Our new ASD WGS study is published. It’s from 242 Korean ASD famiies, a whole new cohort for the field. The phase 2 data (~640 families) is on the way for noncoding mutations but also rare variants, PRS in East Asian cohort. https://t.co/JGboW2JxQE

In the same thread, he pointed out that it is hard to receive funding for autism research in Korea, even though “we know that non-European population is needed for genomics.”
It is even harder for ASD study in our country – only 5 grants were available for ASD over the last 10 years. Hope it’s good transition for ASD and other neuropsychiatric research.

In a reply, Jack Kosmicki, a statistician at Regeneron Genetics Center in Tarrytown, New York, remarked that the lack of funding is disturbing and asked, “Is that unique to ASD or does it expand to other neuropsych disorders?”
Well that’s disturbing – is that unique to ASD or does it expand to other neuropsych disorders?

“It’s for most neuropsych disorders,” An replied, pointing out that more experience is needed in large-scale genomics. “It’s not very common in our country (partly because hard to get fund in this kind of research).”
As you know, we need more experience and generation trained in large-scale genomics or consortium. It’s not very common in our country (partly because hard to get fund in this kind of research).

In a separate thread, Robyn Wootton, a genetic epidemiologist at Lovisenberg Diakonale Sykehus in Norway, shared her paper in which she and her colleagues assessed the association between polygenic scores for autism, and several other neurodevelopmental conditions, and 37 pregnancy-related predisposing factors.
Our new paper, out now in JAMA Psychiatry, shows the importance of considering genetic confounding when exploring the association between pregnancy variables and neurodevelopmental conditions in offspring: ????https://t.co/Qv11yjDNoD (????, 1/8)
— Robyn Wootton (@RobynWootton) August 1, 2022
The study results showed that “polygenic scores for ADHD, autism and schizophrenia were associated with many of these pregnancy variables. Therefore, the association between the pregnancy variables and offspring neurodevelopmental conditions might not be causal.” Wootton tweeted that the results “indicate that future studies exploring pregnancy risk factors for ADHD, autism and schizophrenia need to account for this genetic confounding.”
Our results indicate that future studies exploring pregnancy risk factors for ADHD, autism and schizophrenia need to account for this genetic confounding. (5/8)

“Fascinating paper!” Brian K. Lee, associate professor of epidemiology and biostatistics at Drexel University in Philadelphia, Pennsylvania, said in a quote tweet, reiterating the central point.
Fascinating paper! Maternal genetic liability to ASD, ADHD, SCZ is assoc with classic risk factors for neurodevelopmental disorders, like medications, nutritional supplements, and BMI. Implication being that, e,g. maternal obesity –> NDD may be genetic confounding. 1/2 https://t.co/iud552m6RC

In another quote tweet, Jonathan Roiser, professor of neuroscience and mental health at University College London in the United Kingdom, called the paper “incredibly important work on genetic confounding from the MoBa dataset,” pointing out that many neuroscientists are unfamiliar with this issue that “is going to become a big deal over the next few years.”
Incredibly important work on genetic confounding from the MoBa dataset. Many neuroscientists are unfamiliar with this issue (basically gene-env correlation), going to become a big deal over the next few years as more papers from large dev neuro studies eg ABCD come out https://t.co/v9iSPZIo6Z

Spectrum also reported on the research last week.
The week continued with another ‘key context’ paper. In a tweet thread from Susan Kuo, a postdoctoral researcher at the Broad Institute of MIT and Harvard in Cambridge, Massachusetts, she shared details of her cross-sectional study that sought to “understand just how much autistic individuals vary in early developmental milestone progress, such as starting to walk or talk.”
Early development varies enormously in autistic individuals. We clearly have much to learn about the diverse needs of the autistic community in early life, and much to learn about how to better adapt our environments to fit those needs. (1/6)
— Susan Kuo (@susan_kuo_) July 18, 2022
The results demonstrated “substantial developmental variability across different conditions and provides important context for understanding the phenotypic and etiological heterogeneity of autism.”
In the thread, Kuo went on to explain that “we found that autistic children on average reached their milestones 1-20 months later. The delays were longer for later milestones, like speaking, than earlier milestones, like smiling,” when compared with their non-autistic siblings.
Comparing 17,000+ autistic children and 4,000+ siblings without an autism diagnosis, we found that autistic children on average reached their milestones 1-20 months later. The delays were longer for later milestones, like speaking, than earlier milestones, like smiling. (3/6)

In a reply, Alycia Halladay, chief science officer of the Autism Science Foundation, asked if the researchers had found a difference between boys and girls in the study, also thanking Kuo for “not just the paper but breaking it down on social media (of all places).”
Thank you so much for not just the paper but breaking it down on social media (of all places). Was there a difference in M vs. F overall? Can you describe the direction in the sex diff in those with IDD? THANKS!!!

“Important findings … on developmental variability in a study of over 17,000 autistic children,” tweeted the Center for Genomic Medicine at Massachusetts General Hospital in a quote tweet.
Important findings from the lab of @CGM_MGH faculty @eliserobinson on developmental variability in a study of over 17,000 autistic children. First author @susan_kuo_ provides a nice ???? here explaining the results in @JAMAPediatrics. https://t.co/9CsD2D4Fxf

Stay tuned for Spectrum’s Q&A with Kuo and her adviser, Elise Robinson, about the paper next week.
And finally, it’s time for a ‘study break’: One intriguing thread explored language and thought in a debate that would be right at home in a lecture hall or late-night, deep-thought discussion session in the dorms.
“The relationship between language and thought has long been pondered and debated. It may be one of the deepest and most exciting questions in cognitive science,” wrote Ev Fedorenko, associate professor of psychiatry at the Massachusetts Institute of Technology, who started the thread that soon grew into a huge discussion.
As promised, a????on language and thought. The relationship between language and thought has long been pondered and debated. It may be one of the deepest and most exciting questions in cognitive science. 1/n

Here are some highlights, but the thread is worth checking out in full.
“Do we need language to think? Does language we speak influence how we think? Wrapping up thoughts on four questions on language and thought,” pondered Aleksandra Dobrego, doctoral researcher in cognitive linguistics at the University of Helsinki in Finland, in a quote tweet.

“I think this is a great starting point for attempts to classify the more specific/subtle affects in which language can affect thought,” tweeted Michael Pleyer, assistant professor at the Faculty of Humanities at Nicolaus Copernicus University in Toruń, Poland.
Great thread on language and thought. I think this is a great starting point for attempts to classify the more specific/subtle affects in which language can affect thought, as in this graph by Wolff & Holmes (2011) https://t.co/nVeV5jtJSW (pdf) 1/ https://t.co/lRSki80QXn pic.twitter.com/PKepmZ581c

Richard Firth-Godbehere, author of “A Human History of Emotion,” tweeted that he found the thread interesting, with a small caveat: “I do believe emotion research demonstrates that language has a more profound effect on how we perceive the world than Ev suggests here.”
