Low-pass genome-wide sequencing and variant inference using identity-by-descent in an isolated human populationA Gusev
Department of Computer Science, Columbia University, New York, New York 10027, USA
Genetics 190:679-89. 2012..6% and 97.3%, respectively. This study presents whole-genome analysis of a homogenous isolate population with emphasis on optimal rare variant inference...
Highly scalable genotype phasing by entropy minimizationAlexander Gusev
Computer Science Department, Columbia University, New York, NY 10027, USA

Whole population, genome-wide mapping of hidden relatednessAlexander Gusev
Department of Computer Science, Columbia University, New York, New York 10027, USA
Genome Res 19:318-26. 2009..This finding is supported by concordance of detected deletions with other evidence from independent databases and statistical analyses of fluorescence intensity not used by GERMLINE...
Increased power of mixed models facilitates association mapping of 10 loci for metabolic traits in an isolated populationEimear E Kenny
Department of Computer Science, Columbia University, 505 Computer Science Building, 1214 Amsterdam Ave Mailcode 0401, New York, NY 10027 7003, USA
Hum Mol Genet 20:827-39. 2011..Finally, we report a novel associations for height (rs17629022, P< 2.1 × 10⁻⁸)...
DASH: a method for identical-by-descent haplotype mapping uncovers association with recent variationAlexander Gusev
Department of Computer Science, Columbia University, New York, NY 10027, USA
Am J Hum Genet 88:706-17. 2011..We have replicated one of these loci in an independent European cohort and identified putative structural changes in low-pass whole-genome sequence of the cluster carriers...
Systematic haplotype analysis resolves a complex plasma plant sterol locus on the Micronesian Island of KosraeEimear E Kenny
Rockefeller University, New York, NY 10065, USA
Proc Natl Acad Sci U S A 106:13886-91. 2009..These findings exemplify the power of haplotype analysis for mapping mutations in isolated populations and specifically for dissecting effects of multiple variants of the same locus...
Detecting identity by descent and homozygosity mapping in whole-exome sequencing dataZhong Zhuang
Department of Computer Science, Columbia University, New York, NY, USA
PLoS ONE 7:e47618. 2012..We hypothesize that the variable coverage and platform biases of exome capture account for this decreased accuracy and look toward whole genome sequencing data as a higher quality source for detecting population-wide IBD...
The architecture of long-range haplotypes shared within and across populationsAlexander Gusev
Department of Computer Science, Columbia University, New York, New York, USA
Mol Biol Evol 29:473-86. 2012..These are inconsistent with recent relatedness and suggest ancient common ancestry, with limited recombination between haplotypes...
HLA type inference via haplotypes identical by descentManu N Setty
Computational Biology Program, Memorial Sloan Kettering Cancer Center, New York, New York, USA
J Comput Biol 18:483-93. 2011..We compare our method to a tag SNP-based approach, and demonstrate higher sensitivity and specificity. Our method demonstrates the power of using shared haplotype segments for large-scale imputation at the HLA locus...
