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...

Area of Science:

Biomedical data science
Computational biology
Osteoarthritis research

Background:

Osteoarthritis (OA) is a complex, multifactorial disease.
High-dimensional omic data offers insights into OA pathogenesis.
Integrating omic data is crucial for understanding OA.

Purpose of the Study:

To review recent applications of machine learning (ML) in analyzing single and integrative multi-omic data for osteoarthritis (OA).
To identify emerging trends, challenges, and opportunities in ML-driven OA research.

Main Methods:

Literature search of PubMed and preprint databases up to April 2025.
Identified studies using ML techniques (supervised, unsupervised, deep learning, integrative modeling) on OA omic datasets (transcriptomic, epigenomic, proteomic, metabolomic, multi-omic).
Synthesized findings across omic types, ML methods, and OA outcomes, focusing on multi-omic integration.

Main Results:

ML has been used to discover OA biomarkers, stratify patient subtypes, and predict disease progression.
Advanced ML models like variational autoencoders and multimodal transformers are emerging for multi-omic integration.
Challenges include small sample sizes, overfitting, lack of validation, interpretability, and demographic bias.

Conclusions:

ML techniques enable sophisticated analysis of complex omic data in OA research.
Addressing limitations and adopting new methods like spatial omics and federated learning are key.
Full potential of multi-omic integration for personalized OA diagnosis and treatment requires further development.
