Summary

The intrinsic asthma (atopic or not) is a particular phenotype marked by an early later symptoms, increased severity, sensitivity associated with nonsteroidal anti-inflammatory drugs (NSAIDs), a sinonasal polyposis and eosinophilia.

Unlike allergic asthma, this form does not today demonstrated its genetic character. However, the existence of familial forms of asthma in this region Pays de La Loire led us to hypothesize the existence of genetic variations can explain some familial forms of non-atopic asthma. Corresponding genes may be relevant to understanding the pathophysiological pathways involved in the more common sporadic forms.

The investigators propose a study combining genetic linkage analysis and complete sequencing exomes to identify one or more genetic abnormalities associated with non-atopic asthma. The clinical stage essential for mutation identification is to identify and recruit large families with members affected by non-atopic asthma and ensure accurate phenotyping of all individuals recruited over several generations.

The aim of this study is to create a cohort of families who have more members within them non-atopic asthma. A high genetic combined exome sequencing throughput analysis in a family linkage study will then reveal the presence or absence of genetic variations associated with intrinsic asthma.
