Variant calling in WES vs WGS

Question

[fifty_fifty]

I used SnpEff tool to annotate variants in whole exome sequencing data. However, most variants in the results came out as intron and intergenic variant types. What can be the reason behind it?

I couldn't find a specific command for WES data in the snpEff documentation, so I ran the default command using the latest gene annotation file for my species.

today I learned there were non-human exome kits

i guess model organisms would be very conserved in gene coding regions?

It all depends on the capture as well. It could be because of Agilent Sureselect V8 + NCV

Even otherwise, that is a good news as genetic variation is best seen in NC regions
