Saguenay–Lac-Saint-Jean Asthma Family Cohort Genomic Data from Illumina 610K Arrays

Genomic data for 1,198 individuals from a family asthma cohort in the Saguenay–Lac-Saint-Jean region, used to study genetic and environmental risk and protective factors. The dataset includes Illumina 610K Quad array chip data with imputations based on reference sequences from the UK10K and 1000 Genomes Project. It was authored by Catherine Laprise and last updated on 2026-04 25.

Use Cases

• Identify genetic variants associated with asthma risk based on Illumina 610K Quad array data.
• Study gene-environment interactions for asthma using data from a defined family cohort.
• Perform imputation and downstream GWAS analyses leveraging the UK10K and 1000 Genomes Project reference panels.
• Investigate familial aggregation and heritability of asthma within a geographically isolated population.

Strengths

• Includes data for 1,198 individuals, providing a substantial sample size for genetic studies.
• Data is imputed using high-quality reference sequences from the UK10K and 1000 Genomes Project.
• Focuses on a family-based cohort, which can be powerful for detecting genetic associations.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific analytical needs.
• Data may reflect geographic bias inherent to the Saguenay–Lac-Saint-Jean cohort population.
