I am looking at the GTex portal for significantly different expression of certain genes, within individual tissue types. Is this the same thing as saying that the gene has a significant normalized effect size associated with an eQTL in a tissue? (For instance: https://gtexportal.org/home/gene/PTEN#eQTLBlock)
I'm having trouble figuring out how the eQTL plays in, vs. SNP vs. plain old normalized transcript counts. I'm not sure why SNPs and variants come into play. Thank you!!
