How to exclude readthrough gene after fusion detection

Question

[bio_elle]

I am looking for gene fusions in RNA data and I would like to exclude fusions that could be readthroughs.

I tried to look online for a list of known read through genes but I did not find it.

I was thinking of excluding fusions where the two genes are on the same chromosome and have coordinates close to each other, but I am not sure how to define 'close', since the distance between two genes is not always the same.
