Abstract

The etiology of many human diseases is complex and very likely involves a combination of genetic and environmental risk factors. A popular strategy to detect genetic risk factors is to perform a systematic screening of the genome searching for linkage. The power of such and approach depends very much on the unknown characteristics of the genetic factors and the main difficulty is to establish a good trade‐off between false positives and false negatives. Besides, a precise localisation of the risk factor will generally not be obtained. The set up of a candidate gene stratery is necessary to go further in genetic factor identification. It is likely that for multicfactorioal diseases the only genetic risk factors that can be detected are those with fairly strong effect. Even in that case, it is important to design strategies which increase the power of detection and provide for a better evaluation of the associated risks. La majorité des maladies humaines ont une étiologic complexe et résultent, de I'interaction de facteurs génétiques, etd' environnment. Une stratégic, populaire pour détecter; des cacteurs de risque est la recherche systématique, de liaison sur le génome. La puissance d' une telle approch dépend essentiellement des caractéristiques, inconnues des facteurs génétiques, et la difficultéprincipale est d'établir un bon cornpromis entre faux positifs et faux négatifs. PPar ailleurs, elle ne permet généralement pas de locatiser de facon préciseles facteurs génétiques, impliqués. La misc en place d'une stratégic, de géne candidat est nécessaire pour avancer vers I; identificatin d' un facteur de risque génétique. IIest vraisemblable que pour les maladies multifactorielles, seuls les facteurs ayant un effet immportant pourront étre, détecté. Méme, dans ce cas, il est important de mettre enpalce des stratégies, qui donnent une pussance maximum de détection, et permettent d' évaluer au mieux les risques associés.
