Objective:

To investigate the relationship between genetic risks for ADHD and ASD and clinical symptoms, specifically focusing on antipsychotic responsiveness in patients with schizophrenia.

Approach:

Key Findings:

• The ARS of positive symptoms showed a suggestive negative correlation with ADHD-PRS and a positive correlation with ASD-PRS, although these associations did not survive multiple testing correction.
• No correlation was found between ARS of general psychopathology or negative symptoms and either PRS.
• Identified 1,773 differentially expressed genes (DEGs) related to neuropsychiatric disorders, enriched in neuronal and mitochondrial pathways.

Interpretation:

Genomic risk for neurodevelopmental disorders may influence antipsychotic responsiveness in schizophrenia, indicating potential molecular markers for this phenotype that warrant further exploration.

Limitations:

• Limited sample size restricts the generalizability of findings, particularly in terms of the robustness of the correlations observed.
• Exploratory nature of the study requires further validation in larger cohorts to confirm the findings.

Conclusion:

Further investigation is needed to confirm the findings and explore the implications of genetic vulnerability in schizophrenia treatment, particularly focusing on specific molecular pathways.
