I have a list of amplified genes with genomic intervals and would like to visualise the specific part of gene that is affected. Is there a way to plot a gene and highlight the region of interest? I was thinking a plot with introns and exons of the genes and genomic interval at the bottom with a box highlighting the region of interest but I have no idea how to go about it. Any guidance would be greatly appreciated.

Here is an example of an interval which contains the first few exons of EGFR: chr7:55234427-53437292 (hg19)

Maybe give ggtranscript a go

ggtranscript seems to be a quite neat new package. The alternative, that is around a bit longer, is Gviz, but you can't straightforwardly combine it with ggplot. To highlight the region of interest, you could either use the Annotation track or the Highlight track.

Thank you for the suggestions! I will give these a try.
