Phenolyzer is a software that implements phenotype-based prioritization of candidate genes for human diseases.
Prior biological knowledge and phenotype information may help pinpoint disease contributory genes in whole genome/exome sequencing studies on human diseases. We developed a computational tool called Phenolyzer, which follows a biologist's natural thought processes through four steps: term interpretation, seed gene generation, seed gene growth and data integration. Compared to competing approaches, Phenolyzer has superior performance on finding known disease genes, and on prioritizing recently published novel disease genes.
Phenolyzer is also available as a web-sever at here.

Please clone the repository into your computer:
git clone https://github.com/WGLab/phenolyzer
Then enter phenolyzer directory:
cd phenolyzer
Put your own addon databases into lib/compiled_database. For details of how to use your own Addon databases, please refer to FAQ
Use
-addon [Gene-disease database file name, delimited by comma] -addon_weight [default:1] -addon_gg [Gene-gene database file name, delimited by comma] -addon_gg_weight [default:1]
- Download the databases for CNV annotation (No need to do this for other functions)
perl bin/annotate.pl -downdb -buildver hg19 -webfrom annovar refGene lib/humandb
perl bin/annotate.pl -downdb -buildver hg18 -webfrom annovar refGene lib/humandb
- Print help message
perl disease_annotation.pl --help
- Prioritize 'Alzheimer' genes:
perl disease_annotation.pl alzheimer -p -ph -logistic -out out/alzheimer/out
- Use the disease terms in 'example_disease.txt' file (without phenotype expansion):
perl disease_annotation.pl example_disease.txt -f -p -logistic -out out/disease/out
- Use the phenotype terms in 'example_phenotype.txt' file:
perl disease_annotation.pl example_phenotype.txt -f -p -ph -logistic -out out/phenotype/out
- Use the cnv.bed region:
perl disease_annotation.pl alzheimer -bedfile cnv.bed -p -ph -logistic -out out/alzheimer_cnv/out
- Use the Mentha gene-gene interaction database as Addon
perl disease_annotation.pl alzheimer -p -ph -logistic -out out/alzheimer_addon/out -addon_gg DB_MENTHA_GENE_GENE_INTERACTION -addon_gg_weight 0.05
- To generate exactly the same result as Phenolyzer web server default settings
perl disease_annotation.pl alzheimer -p -ph -logistic -out out/alzheimer_addon_all/out -addon DB_DISGENET_GENE_DISEASE_SCORE,DB_GAD_GENE_DISEASE_SCORE -addon_weight 0.25
- Integrate with wANNOVAR output to prioritize variant
perl calculate_score.pl <phenolyzer_gene_list> <wannovar_genome_summary.txt>
- Input multiple diseases (alzheimer and brain)
perl disease_annotation.pl "alzheimer;brain" -p -ph -logistic -out out/sd
- Parallelize phenotype processing to speed up calculations (fork subprocesses)
perl disease_annotation.pl "alzheimer;brain" -p -ph -logistic -nproc 2
- Use precalculated HPO term expansion and gene scores to speed up calculation. This requires the
unzipcommand to be available in your system. Alzheimer and brain would be processed in parallel and the HPO terms would be pulled from the DB included in phenolyzer.
perl disease_annotation.pl "alzheimer;brain;HP:0004322;HP:0002240" -p -ph -logistic -nproc 2 -use_precalc
