Genome-wide Association Studies-GWAS

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Behavioral Genetics and Its Designs

Behavior genetics explores how genetic inheritance influences human behavior. It focuses on how genes, passed from parents to offspring, contribute to the development of behavioral traits and tendencies. This branch of genetics seeks to understand the complex interplay between inherited genetic factors and environmental influences in shaping our behaviors.
The primary methodologies used in behavior genetics include family studies, twin studies, and adoption studies, each providing unique...

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:

Genome-wide association studies (GWAS) reveal genetic underpinnings of complex traits but often lack diversity.
Under-representation of non-European ancestries in genetic research creates a critical gap in disease prediction.
Multiomic data offers potential to bridge this gap and improve health equity.

Conclusions:

Multiomic data and advanced modeling techniques, including interaction terms and pre-training, can enhance disease prediction accuracy.
Improvements were disease-specific and yielded moderate gains, highlighting the need for further research.
Addressing ancestry gaps in genetic data is essential for equitable and effective disease prediction across populations.
