From: A comprehensive evaluation of ensembl, RefSeq, and UCSC annotations in the context of RNA-seq read mapping and gene quantification

Figure 6

The different gene definitions for PIK3CA give rise to differences in gene quantification. PIK3CA in the Ensembl annotation is much longer than its definition in RefGene, explaining why there are 1094 reads mapped to PIK3CA in Ensembl, while only 492 reads are mapped in RefGene. The PIK3CA gene definition in Ensembl seems more accurate than the one in RefGene, based upon the mapping profile of sequence reads.
