AFAIK, there is not an official list of housekeeping genes anywhere.  I
know that some genes are popular to use for this purpose (ubiquitin for
example) but I don't think there is an official list anywhere.  If there
is one, I would love to know about it. 

But do you really need an official list if you have a good sized data
set?  Perhaps you only need to just find genes that do not vary much
across your dataset.  Maybe you might want to look at the varFilter
function in the geneFilter package? 

library("genefilter")
?varFilter

Hope this helps,
