Analysis of whole genome sequence data shows association of Alzheimer’s disease with rare coding variants in ABCA7 , PSEN1 , SORL1 and TREM2

| Shrnutí: | Previous studies have reported associations between risk of Alzheimer's disease (AD) or dementia and rare coding variants in a number of genes. A two-stage strategy was used in which a previously released whole exome sequenced sample was used to prioritise 100 genes showing the strongest evidence for association with AD. These genes were then analysed in a newly released whole genome sequenced sample to identify those which showed statistically significant evidence for rare coding variant association. Association analysis of loss of function (LOF) and nonsynonymous variants was carried out in 18,998 protein-coding genes using 11,188 controls and 5,808 cases, with nonsynonymous variants being annotated using 45 different pathogenicity predictors. The 100 genes showing strongest evidence for association were then analysed in a new sample of 27,749 controls and 13,234 cases using only the pathogenicity predictor which had performed best in the first sample. Four genes were statistically significant after correction for multiple testing:
,
,
and
. The association of different categories of variant with AD was characterised and the pattern was seen to vary between genes. This study quantifies the contribution of different types of variant within each gene to AD risk. In general, these variants are probably too rare to be clinically useful for assessing individual risk of AD. Further research into the mechanisms whereby the products of these genes affect AD pathogenesis may aid development of novel therapeutic strategies. |
