Evaluation of Genotype-Based Gene Expression Model Performance: A Cross-Framework and Cross-Dataset Study.

Abstract excerpt

Predicting gene expression from genotyped data is valuable for studying inaccessible tissues such as the brain. Herein we present eGenScore, a polygenic/poly-variation method, and compare it with PrediXcan, a method based on regularized linear regression using elastic nets. While both methods have the same purpose of predicting gene expression based on genotype, they carry important methodological differences. We...
