Hi Kurinji,

The IDs in your data set seem to be Entrez gene IDs, not UCSC.  Though I 
wasn't familiar with DAVID, I took a look and it looks like they list 
both Entrez and UCSC gene IDs as supported. In any case, you can use 
these Entrez IDs to get the gene symbol using our table browser: 
http://genome.ucsc.edu/cgi-bin/hgTables

Use the following (I believe these are mm9 ids?):
group: all tables
db: mm9?
table: knownToLocusLink  (note: Locus Link = Entrez)
filter: ...create a filter and paste a space separated list of your 
Entrez Gene IDs in the value field (e.g. value [does] match [22410 22411 
22638 ....])  I know the field is small, but you can paste a long list 
in there.
output format: selected fields from primary and related tables

click "get output"

In the linked tables list, check "kgXref" then scroll to bottom and 
click "Allow Selection From Checked Tables"

Scroll up and check off "name" and "value" from knownToLocusLink, and 
"geneSymbol" from kgXref.

Click get output.
