screen-shot-2016-10-06-at-10-52-29-pmRareIBD is a rare variant association method for extended pedigrees. It supports large pedigrees with  arbitrary structure, binary and quantitative traits, missing individuals in top generations, and affected only pedigrees. The software will be available soon (Sul et al., Under Review).


Screen Shot 2016-01-26 at 10.21.59 AMeGene-MVN is an efficient and accurate multivariate normal sampling (MVN) approach to perform the multiple testing correction in eQTL studies. Our approach is more than 100 times faster than the permutation test when sample size is 2,000. (Sul et al., 2015)


Screen Shot 2016-01-26 at 10.21.43 AMMeta-Tissue is software for identifying eQTLs from multiple tissues. It uses meta-analysis to combine results from multiple tissues, and is a powerful approach to detect eQTLs shared across multiple tissues. (Sul et al., 2013)

RWAS, LRT, VST for rare variants analysis

Screen Shot 2016-01-26 at 10.21.37 AMWe developed statistical methods to detect associations of groups of rare variants. Those two methods are RWAS (Rare variant Weighted Aggregate Statistic), and LRT (Likelihood Ratio Test). We also developed methods to detect associations of rare variants under low-coverage sequencing or pooling. (Sul et al., 2011), (Sul et al., 2011), (Navon et al., 2013)
