Using reported parental disease history to decipher the genetics of Alzheimer’s disease may be promising, but this approach is also susceptible to complex selection and information bias that can mislead researchers if not accounted for.

Correction to: Nature Communications https://doi.org/10.1038/s41467-023-36392-5, published online 15 February 2023The original version of this article contained an error in the second paragraph of the ‘Assay of DBP concentration’ section of the ‘Methods’, which incorrectly read ‘The lower and upper detection limits for DBP were 2.07 and 79.8 mg/L respectively’. The correct version states ‘2.07 µg/L’ in place of ‘2.07’. This has been corrected in both the PDF and HTML versions of the article.

AbstractIt remains inconclusive whether postpartum depression (PPD) and depression with onset outside the postpartum period (MDD) are genetically distinct disorders. We aimed to investigate whether polygenic risk scores (PGSs) for major mental disorders differ between PPD cases and MDD cases in a nested case-control study of 50,057 women born from 1981 to 1997 in the iPSYCH2015 sample in Demark.

AbstractA well-functioning placenta is essential for fetal and maternal health throughout pregnancy. Using placental weight as a proxy for placental growth, we report genome-wide association analyses in the fetal (n = 65,405), maternal (n = 61,228) and paternal (n = 52,392) genomes, yielding 40 independent association signals. Twenty-six signals are classified as fetal, four maternal and three fetal and maternal. A maternal parent-of-origin effect is seen near KCNQ1.

AbstractDepression is a common psychiatric disorder and a leading cause of disability worldwide. Here we conducted a genome-wide association study meta-analysis of six datasets, including >1.3 million individuals (371,184 with depression) and identified 243 risk loci. Overall, 64 loci were new, including genes encoding glutamate and GABA receptors, which are targets for antidepressant drugs.
