- The UCSC Cancer Genomics Browser Has a New Look!
The UCSC Cancer Genomics group has recently remodeled the interface of the
Cancer Genomics Browser
to make it easier to navigate and more intuitive to display, investigate, and
analyze cancer genomics data and
associated clinical information. This tool provides access to many types of
information—biological pathways, collections of genes, genomic and clinical
information—that can be used to sort, aggregate, and perform statistical
tests on a group of samples.
The Cancer Browser currently displays 473 datasets of 25 cancers from
The Cancer Genome Atlas
(TCGA) as well as data from the
Line Encyclopedia (CCLE) and Stand Up To Cancer.
You can find more information about how to use this tool in the online

- dbSNP 137 Available for mm10:
We are pleased to announce the release of three tracks derived
from dbSNP build 137, available on the mouse assembly (GRCm38/mm10).
dbSNP build 137 is available at NCBI. The new tracks contain
additional annotation data not included in previous dbSNP tracks,
with corresponding coloring and filtering options in the Genome

Denisova tracks released on hg19 browser:
In conjunction with the publication of the paper by Meyer et al.
A High-Coverage Genome Sequence from an Archaic Denisovan Individual,
the UCSC Genome Browser is hosting a set of new tracks.

The sequence and annotation data displayed in the Genome Browser
are freely available for any use
with the following conditions:
- Genome sequence data use restrictions are noted within the
species sections on the Credits
- Some annotation tracks contributed by external collaborators
contain proprietary data that have specific use restrictions. To
check for restrictions associated with a particular genome assembly,
review the database/README.txt file in the assembly's
The UCSC, Ensembl, and NCBI browser and annotation groups
have established a common set of minimum requirements for
public display of genome data made available after Spring
The Genome Browser and Blat software are free for academic,
nonprofit, and personal use. A license is required for commercial use.
See the Licenses page for more information.
Program-driven use of this software is limited to a maximum of one
hit every 15 seconds and no more than 5,000 hits per day.
