Hi Li,
If you go to the table browser (http://genome.ucsc.edu/cgi-bin/hgTables)
select the knownGene table and click the "describe table schema" it will
show you how many records (genes) are in the table. There are no
duplicates in this table:
mysql> SELECT name, COUNT(*) AS Count
-> FROM knownGene
-> GROUP BY name
-> HAVING Count > 1;
Empty set (0.03 sec)
Keep in mind that this is not necessarily the complete set of genes in
humans. UCSC Genes is a fairly conservative set of "known" genes. Other
gene sets may contain greater or fewer numbers of genes.
Please let us know if you have any additional questions: [email protected]
