SNP & Variation Suite — Cohort Analysis of Microarray & Sequencing Data
Powerful GWAS software for population genetics, cohort analysis, and research-scale genomic studies. Perform complex analysis and visualization on thousands of samples without requiring programming expertise.
Genome-wide association studies (GWAS) and cohort analysis are essential for identifying genetic variants linked to disease and complex traits. As sample sizes grow into the tens of thousands, researchers require robust GWAS software that provides the statistical rigor necessary for discovery across massive datasets.
Golden Helix SNP & Variation Suite (SVS) is a powerful SNP analysis software platform that delivers complex cohort genomic analysis through an intuitive interface. By eliminating the need for programming expertise, SVS empowers researchers to perform advanced statistics and visualize findings with ease.
What Is GWAS & Cohort Analysis?
GWAS identifies disease-susceptible genes by comparing the genetic variants of individuals with a specific trait or disease against a control group. This approach pair effective analytical methods with an understanding of genetic variation to identify variants related to disease genes.
- Genotype Association Testing: Testing for association against dichotomous or quantitative traits using various genetic model assumptions.
- Population Stratification: Detecting and correcting for ancestry-driven differences that can lead to false positive results.
- Linkage Disequilibrium (LD): Analyzing how variants are inherited together to identify haplotype blocks and functional regions.
Why Population Genomics Matters
Advanced population genetics software allows researchers to move beyond single marker associations to understand the polygenic nature of complex diseases and traits.
Whether you are working in human genetics, agricultural genomics, or veterinary research, the ability to analyze thousands of samples at once enables:
- Polygenic Risk Scores (PRS): Identifying correlations between genotypic variants and phenotypes across large populations for predictive modeling.
- Genomic Prediction: Determining which animals or plants merit breeding for desired traits based on estimated breeding values.
- Imputation: Scaling analysis from common variants to rare variants by imputing missing genotypes using high-density reference panels.
