The most significant results were reported in a sample of autopsy\u2010confirmed families. Linkage to this locus has been independently confirmed in AD families from a consanguineous Israeli\u2010Arab community. In the present study we analyzed an expanded clinical sample of 674 late\u2010onset AD families, independently ascertained by three different consortia. Sample subsets were stratified by site and autopsy\u2010confirmation. Linkage analysis of a dense array of SNPs across the chromosomal locus revealed the most significant results in the 166 autopsy\u2010confirmed families of the NIMH sample. Peak HLOD scores of 4.95 at D9S741 and 2.81 at the nearby SNP rs2772677 were obtained in a dominant model. The linked region included the cyclin\u2010dependent kinase inhibitor 2A gene (<jats:italic>CDKN2A<\/jats:italic>), which has been suggested as an AD candidate gene. By re\u2010sequencing all exons in the vicinity of <jats:italic>CDKN2A<\/jats:italic> in 48 AD cases, we identified and genotyped four novel SNPs, including a non\u2010synonymous, a synonymous, and two variations located in untranslated RNA sequences. Family\u2010based allelic and genotypic association analysis yielded significant results in <jats:italic>CDKN2A<\/jats:italic> (rs11515: PDT p = 0.003, genotype\u2010PDT p = 0.014). We conclude that <jats:italic>CDKN2A<\/jats:italic> is a promising new candidate gene potentially contributing to AD susceptibility on chromosome 9p.<\/jats:p>","DOI":"10.1111\/j.1469-1809.2008.00474.x","type":"journal-article","created":{"date-parts":[[2008,8,29]],"date-time":"2008-08-29T03:46:15Z","timestamp":1219981575000},"page":"725-731","source":"Crossref","is-referenced-by-count":42,"title":["Linkage and Association Study of Late\u2010Onset Alzheimer Disease Families Linked to 9p21.3"],"prefix":"10.1111","volume":"72","author":[{"given":"S.","family":"Z\u00fcchner","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.
