International siblings study sheds new light on the nature of the genetics of disease
Press release issued:
Genetic studies aim to find regions of the genome that associate with diseases or other outcomes. A new study has shown that for social traits these genetic effects are due to a mixture of direct effects (e.g. biological effects of DNA), and indirect effects (e.g. family or social environment). Whereas biological traits are mainly driven by direct effects.
The findings suggest large-scale family datasets provide new opportunities to quantify direct effects of genetic variation on human traits and diseases. Looking at sociological questions and genetics together is a powerful tool for understanding why different health and social outcomes happen, providing better insight for potential interventions and treatments.
