The markers were distributed at an average distance of 6.6 cM, covering 70\u201380% of the chromosome. We analyzed the data by the lod score method using five plausible genetic models ranging from dominant to recessive, after testing the power of our sample under the same genetic parameters. The most positive lod score found was 1.51 under a recessive model for the marker D22S278, which is insufficient to conclude linkage. However, an excess of shared alleles in affected siblings (<jats:italic>P<\/jats:italic> &lt; .01) was found for both D22S278 and D22S283. For D22S278, the <jats:italic>A<\/jats:italic> statistic was equal to the lod score (1.51) and therefore did not provide additional evidence for linkage allowing for heterogeneity, but the Liang statistic was more significant (<jats:italic>P<\/jats:italic> = .002). Our results suggest the possibility that the region around D22S278 and D22S283 contains a gene which contributes to the aetiology of schizophrenia. \u00a9 1995 Wiley\u2010Liss, Inc.<\/jats:p>","DOI":"10.1002\/ajmg.1320600210","type":"journal-article","created":{"date-parts":[[2005,6,11]],"date-time":"2005-06-11T18:17:45Z","timestamp":1118513865000},"page":"139-146","source":"Crossref","is-referenced-by-count":68,"title":["Linkage studies on chromosome 22 in familial schizophrenia"],"prefix":"10.1002","volume":"60","author":[{"given":"Homero P.","family":"Vallada","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Gill","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pak","family":"Sham","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lionel C.
