Our program uses high-density SNP genotype data and works in the face of genotyping errors. It works on nuclear family structures with two or more siblings. The program graphically displays allele sharing status for all members in a pedigree and identifies regions that are potentially linked to the underlined diseases according to user-specified inheritance mode and penetrance. Extensive simulations based on the \u03c72 model for recombination show that our program identifies linked regions with high sensitivity and accuracy. Graphical display of allele sharing status helps to detect misspecification of inheritance mode and penetrance, as well as mislabeling or misdiagnosis. Allele sharing determination may represent the future direction of linkage analysis due to its better adaptation to high-density SNP genotyping data.<\/jats:p><jats:p>Availability: \u00a0http:\/\/paed.hku.hk\/uploadarea\/yangwl\/html\/index.html<\/jats:p><jats:p>Contact: \u00a0yangwl@hkucc.hku.hk<\/jats:p><jats:p>Supplementary information: Supplementary data are available at Bioinformatics online.<\/jats:p>","DOI":"10.1093\/bioinformatics\/btm552","type":"journal-article","created":{"date-parts":[[2007,11,18]],"date-time":"2007-11-18T01:26:02Z","timestamp":1195349162000},"page":"86-93","source":"Crossref","is-referenced-by-count":17,"title":["Identification of linked regions using high-density SNP genotype data in linkage analysis"],"prefix":"10.1093","volume":"24","author":[{"given":"Guohui","family":"Lin","sequence":"first","affiliation":[{"name":"1 Department of Computing Science, University of Alberta, Edmonton, Alberta T6G 2E8, Canada, 2Department of Computer Science, City University of Hong Kong, Kowloon, and 3Department of Paediatrics & Adolescent Medicine, LKS Faculty of Medicine, The University of Hong Kong, 21 Sassoon Road, Hong Kong"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhanyong","family":"Wang","sequence":"additional","affiliation":[{"name":"1 Department of Computing Science, University of Alberta, Edmonton, Alberta T6G 2E8, Canada, 2Department of Computer Science, City University of Hong Kong, Kowloon, and 3Department of Paediatrics & Adolescent Medicine, LKS Faculty of Medicine, The University of Hong Kong, 21 Sassoon Road, Hong Kong"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lusheng","family":"Wang","sequence":"additional","affiliation":[{"name":"1 Department of Computing Science, University of Alberta, Edmonton, Alberta T6G 2E8, Canada, 2Department of Computer Science, City University of Hong Kong, Kowloon, and 3Department of Paediatrics & Adolescent Medicine, LKS Faculty of Medicine, The University of Hong Kong, 21 Sassoon Road, Hong Kong"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu-Lung","family":"Lau","sequence":"additional","affiliation":[{"name":"1 Department of Computing Science, University of Alberta, Edmonton, Alberta T6G 2E8, Canada, 2Department of Computer Science, City University of Hong Kong, Kowloon, and 3Department of Paediatrics & Adolescent Medicine, LKS Faculty of Medicine, The University of Hong Kong, 21 Sassoon Road, Hong Kong"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wanling","family":"Yang","sequence":"additional","affiliation":[{"name":"1 Department of Computing Science, University of Alberta, Edmonton, Alberta T6G 2E8, Canada, 2Department of Computer Science, City University of Hong Kong, Kowloon, and 3Department of Paediatrics & Adolescent Medicine, LKS Faculty of Medicine, The University of Hong Kong, 21 Sassoon Road, Hong Kong"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2007,11,17]]},"reference":[{"key":"2023020209470902300_B1","doi-asserted-by":"crossref","first-page":"97","DOI":"10.1038\/ng786","article-title":"Merlin\u2013rapid analysis of dense genetic maps using sparse gene flow trees","volume":"30","author":"Abecasis","year":"2002","journal-title":"Nat.
