Alternative splicing

Alternative splicing
SNPs controlling the abundance of mRNA isoforms for a gene
Similar to SNPs controlling the abundance of expression of a gene (eQTLs)
Gene-Tissue Expression project eQTL data: 49 tissues but small sample sizes (~200-1200)
eqtlGen cohort: whole blood with >30,000 people
Two cohort measures of cross-brain eQTLs
GTEx 10-13 brain tissues (& whole body): eQTLs for ASD, ALZ, & Parkinson’s
In the process, I found the sQTL data…
More tissues for sGenes (GTEx’s chosen top sQTL), but only one SNP
Can consider running SMR for the sGene data to capture breast and brain
Downside is that we can’t test colocalization with only one SNP per gene
Colocalization is a way to gain evidence that the same SNP is causal for both splicing and the GWAS phenotype
Without evidence of a single, underlying “causal” SNP, there is more evidence that the signal is due to genetic architecture (i.e., linkage)
Protein localization to nucleolus (GO:1902570)
Nucleolus organization (GO:0007000)
Regulation of protein localization to nucleolus (GO:1904749)
AmiGO search terms “ribosomal proteins” (cytosolic & mitochondrial ribosomes) & “ribosomal biogenesis”
1. Alzheimer’s disease (ALZ)
2. Autism spectrum disorder (ASD)
3. Education years (EduYears)
4. Forced expiratory volume in 1-second (FEV1)
5. High- and low-grade serous ovarian cancer (HLGOC)
6. High-grade serous ovarian cancer (HGOC)
7. Lung cancer (LC)
8. Ovarian cancer (OC)
9. Parkinson’s disease (PD)
