Hi,
I am looking at a SNP located within the 3'UTR of a gene of interest. I discovered that in a tissue type of interet one of the alleles of the SNP is preferentially expressed over the other in patient samples heterozygous for the SNP. However, when I stratify total gene expression measured by qPCR by genotype in patients, I find that the preferentially expressed allele actually correlates with lower expression.
Does anyone have any idea why this might be happening?
Thank you in advance for your time.
Best wishes,
Tanya
