Oxford genome screen for asthma-associated traits

Area of Science:

• Genetics
• Asthma Research
• Quantitative Trait Linkage

Background:

• Asthma is a complex respiratory condition influenced by multiple genes.
• Identifying genetic factors for asthma is crucial for understanding its pathogenesis.
• Previous genome-wide screens have been conducted on general population samples.

Purpose of the Study:

• To describe the data resources for a genome screen of quantitative traits underlying asthma.
• To facilitate further genetic analysis of asthma in Genetic Analysis Workshop 12.
• To provide a dataset for exploring genetic linkages in asthma phenotypes.

Main Methods:

• Genome screen utilizing 80 families selected for discordant asthma phenotypes.
• Analysis of 203 offspring within these families, forming 172 sib-pairs.
• Genotyping data from 296 genetic markers were employed.

Main Results:

• Detailed description of family ascertainment and phenotypic data collection.
• Presentation of genotypic data for 296 markers across the studied families.
• The dataset is prepared for linkage analysis of asthma-related quantitative traits.

Conclusions:

• The described dataset provides a valuable resource for genetic studies of asthma.
• Further research can utilize these data to identify genes contributing to asthma susceptibility.
• This work supports ongoing efforts in genetic analysis workshops for complex diseases.
