Abstract excerpt
BACKGROUND: The X chromosome plays an important role in human diseases and traits. However, few X-linked associations have been reported in genome-wide association studies, partly due to analytical complications and low statistical power. RESULTS: In this study, we propose tests of X-linked association that capitalize on variance heterogeneity caused by various factors, predominantly the process of...
