 !!! warning
-	To make matters even worse, not only `NM_001135865.1` maps twice to regions in `chr16`, but also one is mapped in the forward strand and the other on the reverse strnad (notice the `+` and `-` signs)

 How do you know which of the four `NM_001135865.1` version is SnpEff refering to?
 When there are multiple mappings for a transcipt SnpEff will make sure each mapping is uniquely identified by appending a number to the original transcript ID.
