Additional comments

The annotation for mir-2b-1 has been changed in release 5.31 of the genome annotation, so that instead of representing a mature miRNA it now represents the precursor stem loop pre-miRNA. The symbol of the annotation has been changed from CR32990 to CR42893 to reflect this change.
