Abstract

As one aspect of the complex feature of longevity, gene-sex interaction plays an important role in influencing human life span. With advances in molecular genetics, more studies aimed at assessing gene-sex interaction are expected. New and valid statistical methods are needed. In this paper, we introduce a nontraditional approach, the case-only design, which was originally proposed for assessing gene and disease associations, to detect gene-sex interaction in human longevity. Applications of this method to data collected from centenarian studies show that it can produce consistent results as compared with results obtained from case-control and other approaches. Important features of the application in human longevity studies are highlighted and discussed. Since centenarians constitute a special population representing successful ageing, the easily applicable case-only approach will be an important tool for screening potential major genes that contribute to human longevity.
