Complex genotype-phenotype relationships in neurodevelopmental disorders.

Genotype-phenotype relationships in neurodevelopmental disorders are highly complex, with diverse clinical outcomes observed even among individuals with the same risk gene variants.

• Why it matters: Understanding this heterogeneity is essential for improving diagnosis and developing personalized treatments, but the factors influencing phenotypic variability remain unclear.
• What they did: The study advocates for integrative approaches combining large-scale genetics, functional genomics, environmental data, and developmental variability assessments to identify modulators of phenotypic outcomes.
• The result: Unraveling these interacting factors will enhance our understanding of NDD etiology and enable more precise diagnostic and therapeutic strategies tailored to individual genetic and environmental profiles.
