Expression Quantitative Trait Loci (eQTL) in Global Populations

Program for Mapping eQTL and
eQTL Database in Global Populations

Introduction

In our eQTL mapping study, transcript expression levels of genes (transcript-level gene; T-gene) are correlated with single nucleotide polymorphisms (SNPs) on a gene (sequence-level gene; S-gene) via a method of gene-based partial least squares (PLS).

PLS method and an illustrative example.

Data archives

Three eQTL data archives including gene- and SNP-based eQTL for four HapMap Phase II populations (YRI, CEU, CHB, and JPT).
