Linking Human Mutations to Phenotype

PhenCode

• Brings the deep information on genotypes and phenotypes in locus specific databases (LSDBs) into a common database

• Uses genome sequence coordinates

• Allows data to be displayed in genome browsers and compared and analyzed with respect to other genome data.

• Collaboration among many LSDBs, Human Genome Variation Society and genome browsers

23 (142) LSDBs

Over 17,000 mutations

Swiss-Prot / UniProt

Over 23,000 mutations

Access to data in PhenCode

• Home Page www.bx.psu.edu/phencode– Query page– History page

• Output can be viewed as – a custom track at UCSC Genome Browser

• (then Table Browser and Genome Graphs)– A custom track at Ensembl– Custom track files for other Genome Browsers– As tab delimited text for downloads

“What LSDB variants are NOT in dbSNP and ARE in conserved

regions?”

• Find substitutions in PhenCode / Locus Variants track

• Remove entries that are already in dbSNP• Remove entries that are not intersected by

the most conserved track (PhastCons)• View results as coverage on genome and

details of an single variant

PhenCode query page

Export the data and view as a track in the UCSC Genome Browser.

The Table Browser can now be used to filter out the entries included in dbSNP or not covered by

the Most Conserved track.

The filters have reduced the numbers, but there are many left.

Genome Graphs shows the coverage of the results

Genome Graphs shows the coverage of the results

Genome Graphs displays the coverage back in the Genome Browser.

A summary can be found at the PhenCode site and more details at the source LSDB.

Conclusion

• The deep annotations from LSDBs compliment the broad annotations from dbSNP

• The data from PhenCode is public and available in genome browsers and as text.– www.bx.psu.edu/phencode
