Hello, The RefSeq sequences at UCSC are directly from the NCBI release. Differences are likely due to the different programs used to generate the alignment. To double check that the mRna is the same, extract the mRNa from the Table browser or the track description page and compare it to the record at NCBI. Also note that the update data is included on the track description page, too. We hope this helps, Jennifer
