arising from C. Cruchaga et al. Nature 505, 550–554 (2014); doi:10.1038/nature12825

Cruchaga et al. recently reported1 evidence for genetic association between Alzheimer's disease risk and several rare DNA sequence variants in the phospholipase D3 gene (PLD3). The study's lead signal Val232Met (rs145999145) co-segregated with Alzheimer's disease in multiple affected families, and also showed association with Alzheimer's disease risk in case–control samples; whereas two other highly conserved PLD3 variants, Ala442Ala (rs4819) and Met6Arg, showed nominal association with disease risk. Our efforts to replicate these findings in a large collection of family-based Alzheimer's disease data failed to reveal any risk effect of PLD3 in Alzheimer's disease. Our negative results, taken together with equally negative companion reports2,3,4 and recent GWAS meta-analysis results5, call for additional studies to examine the proposed role, if any, of rare variants in PLD3 on Alzheimer's disease risk. There is a Reply to this Brief Communication Arising by Cruchaga, C. & Goate, A. M. Nature 520, http://dx.doi.org/10.1038/nature14041 (2015).
