Abstract: Mendelian randomization (MR) is a method of exploiting genetic variation to unbiasedly estimate a causal effect in the presence of unmeasured confounding. In MR, natural genetic variations are used as instrumental variables to perform causal inference on the effect of heritable risk factors. Because of its convenience, MR has been widely used in epidemiology and other related areas of population science. However, the phenomenon that all genes affect every complex trait complicates Mendelian Randomization (MR) studies as most genetic variants will then be invalid instruments. In the talk, Ill discuss a series of developments using a new comprehensive framework that we developed for MR that can deal with pervasive horizontal pleiotropy, weak genetic instruments, and the temporal relationship between the risk factors and disease progression. Ill also illustrate a few case studies at the end of the talk.
