We examined whether a polygenic score (PGS) for smoking measured genetic risk for general behavioral disinhibition by estimating its associations with externalizing and internalizing psychopathology and related personality traits at multiple time points in adolescence (ages 11, 14, and 17 years; = 3225). The smoking PGS had strong associations with the stable variance across time for all the externalizing measures (mean standardized = .27), agreeableness ( = -.22, 95% CI: -.28, -.16), and conscientiousness ( = -.19, 95% CI: -.24, -.13), but was not significantly associated with internalizing measures (mean = .06) or extraversion ( = .01, 95% CI: -.05, .07). After controlling for smoking at age 17, the associations with externalizing, low agreeableness, and low conscientiousness remained statistically significant. The smoking PGS measures genetic influences that contribute to a spectrum of phenotypes related to behavioral disinhibition including externalizing psychopathology and normal-range personality traits related to behavioral control, but not internalizing psychopathology.

Li-Fraumeni syndrome (LFS) is an early-onset cancer syndrome caused by pathogenic germline TP53 variants. Adolescents and young adults (AYAs) with LFS may have challenges navigating new romantic partnerships given the significant effects of LFS on multiple life domains that also affect partners (e.g.

Objective: In recent decades, increased freedom of choice and advancements in fertility regulation have allowed individuals to follow different fertility paths. This greater autonomy provides room for personality traits to shape long-term fertility expectations, which in turn can be predictive of fertility outcomes. The present study investigates how Big Five personality traits are related to fertility expectations trajectories and outcomes.

Rationale: Clinical innovation-where physicians develop and use novel interventions that differ significantly from standard practice and that have not been shown to be sufficiently safe or effective for regular use in healthcare systems-has the potential to transform patient care and drive medical advancement. However, it is not without risk. It is important, therefore, that policymakers and healthcare institutions develop strategies to encourage responsible clinical innovation.

Objective: The terminal Pleistocene is a crucial stage in the formation and differentiation of modern populations. Recent studies show that the population during this period had significant morphological variability and regional divergence. The objective of this study was to investigate the Yahuai-1 (YH1) from the Yahuai Cave site in southern China to understand human morphological diversity and population dynamics during the terminal Pleistocene in Southern East Asia.

However, the origin of these phenotypes in the general population is poorly understood and their association with the genetic predisposition to psychoses has not yet been proven.
Aim: The aim of this study is to answer the question of whether data on the relations of ST and PENS with polygenic risk scores for schizophrenia (SZ-PRS) support the hypothesis that these phenotypes are subclinical manifestations of genetic liability for schizophrenia.
