(7/8) We then integrated the PA-FGRS with a within-family genetic design. This generally supported core assumptions of the PA-FGRS as a between-family index of risk, though indicated potential influence of non-direct genetic effects for drug use disorder.

Family history has been recognised as a risk factor for psychiatric disorders since the late 18th century. In this new preprint, we leverage family history of psych and neurodev diagnoses to estimate family-genetic risk scores (PA-FGRSs) in the Norwegian population🧵 doi.org/10.31234/osf...

10/11 Caveats: outcomes were maternally reported (possible rater bias). We focused on maternal effects; paternal effects may also matter. Indirect genetic effects are probabilistic and don't identify the specific parenting behaviors to target.
100
Eivind Ystrom @eivindy.bsky.social · 04/02/2026
9/11 Take-home: substantial maternal (parenting-related) contribution across the spectrum; largely one shared dimension; accounting for it matters for interpreting "heritability" and genetic correlations.
100
Eivind Ystrom @eivindy.bsky.social · 04/02/2026
8/11 Example: for oppositional defiant/hyperactivity/inattention, direct genetic variance was ~50-61% when maternal effects were omitted, but ~30-31% when maternal effects were modelled - highlighting confounding potential.
100
Eivind Ystrom @eivindy.bsky.social · 04/02/2026
7/11 Those maternal effects were mostly general: a single underlying maternal factor accounted for most of the maternal influence across both internalizing and externalizing symptoms.
100
Eivind Ystrom @eivindy.bsky.social · 04/02/2026
6/11 Main result: indirect maternal genetic effects explained ~7-18% of variance across these symptom measures.
100
Eivind Ystrom @eivindy.bsky.social · 04/02/2026
5/11 We (i.e. Espen) modeled 7 symptom scales at age 8 (maternal ratings): conduct, oppositional defiant, hyperactivity, inattention, neuroticism, depression, anxiety - plus household effects to separate "family environment" from maternal effects.
100
Eivind Ystrom @eivindy.bsky.social · 04/02/2026
4/11 Data: 42,423 children and 37,418 mothers from the Norwegian Mother, Father and Child Cohort Study (MoBa), combining pedigree links with genotype-based relatedness.
110
Eivind Ystrom @eivindy.bsky.social · 04/02/2026
3/11 Why it matters: if we ignore indirect parental effects, we risk attributing too much to children's direct genetics (and mischaracterizing the structure of genetic risk).
100
Eivind Ystrom @eivindy.bsky.social · 04/02/2026
2/11 Concept: mothers' genes can affect children indirectly via the environment they provide ("genetic nurture") - not about blame, but about pathways beyond direct inheritance.
