Dear Phil,
I'll look into this issue and check if you can do an actual identifier search using the search field on the website (I think so but I am uncertain of the syntax right now).
Currently, you are using the free text search available on the website, which is looking for the text in the pathways but also descriptions, titles and literature references.
Using the following search returns the union of the two searches.
IL6 OR IL-6
If you use IL6 AND IL-6 you can see the 4 pathways that use both spelling versions.
If you want to look for pathways that contain the gene of interest as an actual datanode (element in the pathway), I would advise to use the webservice, PathVisio plugin (search by Xref) or R package (see example code below). You will see that there are 59 pathways containing 103 IL6 datanodes (e.g. WP4122 contains 17 IL-6 datanodes as participants in different complexes).
Hope this helps? Please let me know if you need further information.
Best regards,
Tina
library(rWikiPathways)
library(dplyr)# looking for pathways containing the human IL6 gene
res <- as.data.frame(rWikiPathways::findPathwayIdsByXref("ENSG00000136244","En"))colnames(res) <- "pathway"
# some pathways contain multiple IL6 data nodes - those will be grouped and counted
res.grouped <- res %>% group_by(pathway) %>% summarize(count = n())
