Abstract

The psoriasis is a complex chronic inflammatory skin disease due to a strong genetic component as well as environmental factors. The only major locus for psoriasis susceptibility implicated to date, named PSORS1 on chromosome 6p21, has been demonstrated in various populations in linkage and association studies. It could nevertheless be responsible for up to 50% of the genetic contribution to the disease. The aim of my thesis was thus to identify the other genetic factors, in particular in the French population. To identify the loci, a linkage study was carried out, showing possible regions on 12q, 14q, 16p, 20p, in addition to that on 6p. Two loci on 6p and 20p were studied in more detail, revealing the contribution of the two genes, HLA-C and ADAM33. In parallel, a "candidate gene" strategy was undertaken, exposing a probable role of FLG, TGM5, CARD15 and CYLD genes and a confirmed role of SLC12A8 gene in the etiology of psoriasis.
