Q:

genes with highest RPKM/FPKM for a human RNA-seq experiment?

Which genes/transcripts show up as having the highest RPKM/FPKM on a human RNA-seq experiment? Is it usually the same genes/transcripts?
EDIT: mRNAs (e.g. poly-A RNA-seq preps) and not including small RNAs.

A:

As asked as it is, the answer is probably no.
Indeed, the highest expressed RPKM/FPKMs will be different from one condition (or tissue) to another one for example.
Then, you may also have technical artefacts due to the wet-lab part or to the normalisation. For example, mitochondrial genes are often reported in the top expressed genes.
Now, if you want to compare your results to an outside source, I recommend checking the EBI gene expression Atlas* and more specifically the Baseline expression experiments.
Pro-tips:

You can filter the genes based on their nature (eg, mRNA) and/or their expression.
You can also visualise the overall expression of a specific gene across several experiments.
