Visualizing Genomic Position For Many Genes Graphically.

I only put a table on a poster reluctantly. Here I am hoping to show each of 64 genes we investigated as part of a pathway analysis. I'd like to show where each sits in the genome and possibly next to each the number of SNPs investigated and number significant. A Manhattan is not correct this isn't part of a GWAS. Genome-graphs is similar to what I'm thinking, but doesn't list gene name. What do you all suggest?

Sounds like circos might be useful?

Ahhh... I'll have to look at this site. I've seen spirographs in Nature Genetics before and wondered how they were made.

If this is for a poster, maybe it will be better to pick a handful of interesting genes you want to focus on and graphically display those individually instead of all 64 genes.

Unless you are trying to show some kind of analysis/pattern related to their genomic positions, I don't think plotting all 64 will add to the poster.

I understand this. I think you are right. Perhaps it's just better to show the relationships between those significant associations than genomic positions and SNP number. The only reason I like to see number of SNPs in a given gene or LD patterns is to decide if I believe the result is significant. Here we have the results of a meta-analysis from 9 studies. So we're pretty sure our result is real; but showing each gene may add little value as you say.

Hi,

I think this answer in Biostar (and the others for this question) can be of interest for you. To me it seems it adresses quite well your request.
