Genome-wide Association Analysis Online Inquiry

As one of the providers of genome-wide association analysis, CD Genomics uses bioinformatics to help you achieve efficient mapping of multiple target trait genes quickly and accurately. Our unique data analysis skills can meet customers' personalized data analysis needs and provide easy-to-interpret data analysis reports.

Introduction of Genome-wide Association Analysis

In genetics, a genome-wide association study (GWAS) is an observational study of a genome-wide set of genetic variants in different individuals to investigate whether any variant is associated with a trait. GWASs typically focus on associations between single-nucleotide polymorphisms (SNPs) and traits like major human diseases, but can equally be applied to any other genetic variants and any other organisms.

The most common approach of GWA studies is the case-control setup, which compares two large groups of individuals, one healthy control group and one case group affected by a disease, or one conventional trait control group, and one target trait control group. All individuals in each group are genotyped for the majority of commonly known SNPs. The exact number of SNPs depends on the genotyping technology, but are typically one million or more.
