Human Genetics

Human Genetics

Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...

Background:

Neuropsychiatric disorders represent a growing global health challenge.
Existing pharmacotherapies have limitations, highlighting the need for novel treatment strategies.
High-throughput screening methods for identifying new treatments are scarce.

Purpose of the Study:

To leverage large-scale genetic and health data for drug repurposing in neuropsychiatric disorders.
To identify potential drug candidates for repurposing using Mendelian Randomization (MR).

Main Methods:

Utilized UK Biobank (N=361,141) and FinnGen (N≈410,000) datasets for exposure and outcome data.
Employed Mendelian Randomization (MR) analyses to infer causal relationships.
Conducted sensitivity, Linkage Disequilibrium Score Correlation (LDSC), and Bayesian Colocalization (COLOC) analyses for robustness.

Main Results:

Identified seven medications with negative causal associations with neuropsychiatric disorders via the IVW method.
Specific drugs showed associations with reduced anxiety (Pregabalin, Bumetanide, Prednisolone), dementia (Vitamin B1), epilepsy (Creon E/C granules), multiple sclerosis (Pentasa SR 250 mg), and stroke (Zolmitriptan).
Sensitivity analyses, LDSC, and COLOC supported the reliability of the findings.

Conclusions:

Mendelian Randomization-based drug repurposing is a viable strategy for neuropsychiatric disorders.
The identified medications show potential for clinical application.
Further clinical validation is required to integrate these repurposed drugs into practice.
