Figure 1: Visualizations of correlation for a dataset containing 22,000 variables. The left two images show the correlation coefficients using a heatmap, clustered with (a) average linkage, and (b) complete linkage. The visible patterns in the heatmap are highly dependent on the clustering algorithm. In (c), our novel s-CorrPlot spatially encodes correlation coefficients, highlighting very diff...

To detect association of the DR1 allele with rheumatoid arthritis (RA) given linkage in the affected sibling pairs of the replicates of Problem 3 of Genetic Analysis Workshop 15 (GAW15), we propose a new score statistic that takes into account the linkage information. We knew the answers. Linkage studies are often followed by case-control association studies of candidate genes located under the...

The combined use of the arbitrarily primed polymerase chain reaction [AP-PCR, also known as random amplification of polymorphic DNA (RAPD}] and isozyme mapping resulted in the production of 87 potential marker loci, enabling an overall expansion within the genetic map of the fish genus Xiphophorus. Use of DNA sequencing-style acrylamide gels and carefully controlled conditions of amplification ...

OBJECTIVE: To study the feasibility of making an early diagnosis of adult polycystic kidney disease by using genetic linkage analysis in Hong Kong. DESIGN: Genetic linkage study. SETTING: University teaching hospital, Hong Kong. PARTICIPANTS: Six members of a Chinese family with a history of adult polycystic kidney disease. MAIN OUTCOME MEASURES: The inheritance pattern of adult polycystic kidn...

Etiologic heterogeneity is a fundamental feature of complex disease etiology; genetic linkage analysis methods to map genes for complex traits that acknowledge the presence of genetic heterogeneity are likely to have greater power to identify subtle changes in complex biologic systems. We investigate the use of trait-related covariates to examine evidence for linkage in the presence of heteroge...
