Nearest neighbors from a determinate gene in the module

Question

[cardon.chc]

Dear community,

I am doing a gene co-expression analysis using the R packages WGCNA and igraph for visualization. I have generated all modules and found the hub gene for each one, but, another step I would like to do is find the nearest neighbors of a specific gene that I found in the module. (Example: the 10 most connected genes with this gene), that is not necessarily the hub gene. Also, how to generate a list with only these genes ID.

Please, let me know if need any additional information.

Thank you!

I kindly appreciate your help.
