Dyslexia extends beyond reading difficulties: genetic links with social functioning and well-being

In the Lifelines cohort, genetic liability to dyslexia is linked to lower life satisfaction and reduced collegial support, and Mendelian randomization supports a directional effect toward loneliness and social isolation.

• Why it matters: Dyslexia’s social and emotional impacts are reported, but the genetic relationships among dyslexia, social functioning, and well-being are unclear, limiting targeted support.
• What they did: The study combined Lifelines phenotypes with GWAS summary statistics, using phenotypic and genetic correlation analyses, polygenic score (PGS) testing, linkage disequilibrium score regression (LDSC), and bidirectional two-sample Mendelian randomization.
• The result: Phenotypic and genetic correlations connected dyslexia with lower life satisfaction, higher loneliness, and less collegial support; PGS for dyslexia predicted these outcomes, and bidirectional MR found dyslexia liability increases loneliness and social isolation, with no evidence that social traits causally affect dyslexia.
