Pure and Confounded Effects of Causal SNPs on Longevity: Insights for Proper Interpretation of Research Findings in GWAS of Populations with Different Genetic Structures.

Frontiers in genetics

Yashin AI, Zhbannikov I, Arbeeva L, Arbeev KG, Wu D, Akushevich I, Yashkin A, Kovtun M, Kulminski AM, Stallard E, Kulminskaya I, Ukraintseva S.

Front Genet. 2016 Nov 08;7:188. doi: 10.3389/fgene.2016.00188. eCollection 2016.

This paper shows that the effects of causal SNPs on lifespan, estimated through GWAS, may be confounded and the genetic structure of the study population may be responsible for this effect. Simulation experiments show that levels of linkage disequilibrium...

How Well Does the Family Longevity Selection Score Work: A Validation Test Using the Utah Population Database.

Frontiers in public health
