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...

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:

Sudden death (SD) poses a significant public health challenge.
Identifying reliable biomarkers for SD is crucial for risk assessment and understanding underlying causes.

Purpose of the Study:

To identify significant biomarkers associated with sudden death (SD).
To explore potential genetic markers for predicting SD risk.

Main Methods:

Differential gene screening in whole blood samples from accidental death (AD) and SD cases.
Protein-protein interaction (PPI) network analysis to identify core interacting genes.
Machine learning application for characteristic gene identification.
CIBERSORT method for immune-microenvironment analysis.

Main Results:

Ten core genes (e.g., MYL1, TNNC2, TNNT3, MYL2) were identified, primarily associated with myocarditis and cardiomyopathies.
Machine learning identified MYL2 and TNNT3 as characteristic genes linked to SD.
No significant alterations in the immune-microenvironment were observed in relation to SD.

Conclusions:

Characteristic genes like MYL2 and TNNT3 can aid in identifying individuals at high risk for SD.
These genetic markers may assist in speculating the cause of sudden death.
