What is the Origin of GWAS?

The term is a key abbreviation in modern genetics, combining the concept of "genome-wide" screening with "association studies," which link genetic variations to observable characteristics (phenotypes). GWAS became technologically feasible and widespread in the early 2000s, driven by advancements in high-throughput genotyping.

What is the Mechanism of GWAS?

The study functions by comparing the frequency of hundreds of thousands of genetic markers in two distinct groups: people with a specific condition (cases) and people without it (controls). If a particular SNP is found significantly more often in the case group, it is considered an associated locus. This association points researchers toward the genomic regions and potential genes that contribute to the biological underpinnings of the trait or disease.

GWAS

Meaning

GWAS, or Genome-Wide Association Study, is a powerful research methodology in genomics that systematically scans the entire genome of a large cohort of individuals to identify genetic variants, primarily single nucleotide polymorphisms (SNPs), that are statistically associated with a particular disease or measurable trait. This unbiased approach is instrumental in uncovering the complex genetic architecture of multifactorial conditions. It has revolutionized the study of complex human diseases.
