Twin modelling reveals partly distinct genetic pathways to music enjoyment - Nature Communications Here, Bignardi et al. report on a study of over 9,000 Swedish twins that indicates the ability to enjoy music is influenced by multiple partly distinct genetic factors.

“What an odd thing“ wrote Oliver Sacks “to see an entire species playing with listening to meaningless tonal patterns, preoccupied for much of their time by what they call ‘music’...“. Our new paper, led by ace student @giacomobignardi.bsky.social, unpacks this puzzle from a genetic perspective. 🧪

Many thanks to all of the collaborators and funders (esp
@wellcometrust.bsky.social & @ukri.org) who made this DNA methylome-wide study of antidepressant exposure possible www.nature.com/articles/s41...

Excited to share a couple of new items (links below):
1. Our work on gene-environment interactions in the UKBiobank is up at the American Journal of Human Genetics
2. Our work on modeling ancient human population size history is up at Molecular Biology and Evolution

🚨NEW PAPER! Together with Wuno Akingbuwa (@wonuola.bsky.social) we developed a way to estimate non-linear genetic correlations. It didnt sit well with us that known non-linear relations (e.g. BMI and MDD with a famous U shaped ) are poorly captured in statistical genetics. 🧵

Incredibly proud to see our latest work out in Nature Genetics: www.nature.com/articles/s41...

Here we share our FLAMES framework, which predicts the effector genes in GWAS loci with state-of-the-art precision🔥

Genetic correlations between MDD and each neuroticism cut point. The line of best fit is shown, based on a linear regression model, with parameters estimated using generalized least squares (GLS).

Standardized results (with standard errors) for two-factor genomic structural equation model as estimated using GenomicSEM software.

Are mental disorders extreme manifestations of continuous traits or genetically distinct entities? We present Genomic Taxometric Analysis of Continuous and Case-Control data (GTACCC) for evaluating genetic continuity and differentiation of traits across the severity spectrum. Tweetorial coming soon.

Modern GWAS can identify 1000s of significant hits but it can be hard to turn this into biological insight. What key cellular functions link genetic variation to disease?

Speaking of, this upcoming workshop is free online. You are also very welcome to visit us in Richmond. That would be stellar! 😇

e.g., if you were using mxPath() to specify a path, you'd set free=TRUE and then specify some lbound and ubound values. Of course, you'd need a rationale to constrain the parameter within that range.
openmx.ssri.psu.edu/docs/OpenMx/...

I have only used it in OpenMx openmx.ssri.psu.edu/docs/OpenMx/...
e.g., to keep the correlation estimate between -1 and +1, or to keep the variance estimate positive.
But you can restrict any parameter estimate to be within a range (between "ubound" & "lbound")

@michelnivard.bsky.social, more info?

Setting upper and/or lower bounds for the estimate?

Congratulations, Dan (here, too)! 🥳
