Abstract: Clear evidence exists for heritability of human longevity, and much interest is focused on identifying genes associated with longer lives. To identify such longevity alleles, we performed the largest genome-wide linkage scan thus far reported. Linkage analyses included 2118 nonagenarian Caucasian sibling pairs that have been enrolled in fifteen study centers of eleven European countries as part of the Genetics of Healthy Ageing (GEHA) project. In the joint linkage analyses we observed four regions that show linkage with longevity; chromosome 14q11.2 (LOD=3.47), chromosome 17q12-q22 (LOD=2.95), chromosome 19p13.3-p13.11 (LOD=3.76) and chromosome 19q13.11-q13.32 (LOD=3.57). To fine map these regions linked to longevity, we performed association analysis using GWAS data in a subgroup of 1,228 unrelated nonagenarian and 1,907 geographically matched controls. Using a fixed effect meta-analysis approach, rs4420638 at the TOMM40/APOE/APOC1 gene locus showed significant association with longevity (p-value=9.6 x 10(-8) ). By combined modeling of linkage and association we showed that association of longevity with APOEepsilon4 and APOEepsilon2 alleles explain the linkage at 19q13.11-q13.32 with p-value=0.02 and p-value=1.0 x 10(-5) , respectively. In the largest linkage scan thus far performed for human familial longevity, we confirm that the APOE locus is a longevity gene and that additional longevity loci may be identified at 14q11.2, 17q12-q22 and 19p13.3-p13.11. Since the latter linkage results are not explained by common variants, we suggest that rare variants play an important role in human familial longevity.

Genome-wide linkage scan in 2118 European nonagenarian sibships and younger controls from various European studies followed by genome-wide association study in a subgroup of 1228 unrelated nonagenarian and 1907 geographically matched controls.
Four regions showed linkage to longevity (14q11.2, 17q12-q22, 19p13.3-p13.11 and 19q13.11-q13.32).
