EmbedPVP: Embedding-based Phenotype Variant Predictor

Prioritizing genomic variants through neuro-symbolic, knowledge-enhanced learning.

Annotation data sources (integrated in the candidate SNP prediction workflow)

We integrated the annotations from different sources:

• Gene ontology (GO)
• Mammalian Phenotype ontology (MP)
• Human Phenotype Ontology (HPO)
• Uber-anatomy ontology (UBERON)

Dependencies

• The code was developed and tested using Python 3.9.6

  You need to use any version of Python > 3.9 and < 3.10

• We used (mOWL) library to process the input dataset as well as generate the embedding representation using different embedding-based methods.

  You need to have JAVA and JDK installed in your machine.

Get the data

1. Download all the files from data and place the uncompressed the file in the folder named /data.
2. Download the required database using CADD and follow the instructions to generate the TSV file with CADD scores for the input VCF file.

Use the tool

You can install the tool either from source or PyPi as follows:

Create a virtual environment

python3 -m venv embedpvp_env
source ./embedpvp_env/bin/activate

☑️ Install from source

git clone https://github.com/bio-ontology-research-group/EmbedPVP.git
cd EmbedPVP/
python setup.py install 
mkdir output
embedpvp [args]

☑️ Install from PyPi

pip install embedpvp
mkdir output
embedpvp [args]

• Run the command embedpvp --help to display help and parameters:

Initializing the package
Usage: embedpvp [OPTIONS]

Options:
  -d, --data-root TEXT      Data root folder  [required]
  -i, --in_file TEXT        Annotated Input file  [required]
  -p, --pathogenicity TEXT  Path to the pathogenicity prediction file (CADD)
                            [required]
  -hpo, --hpo TEXT          List of phenotype codes separated by commas
                            [required]
  -m, --model_type TEXT     Ontology model, one of the following (go , mp ,
                            hp, uberon, union)
  -e, --embedding TEXT      Preferred embedding model (e.g. TransD, TransE,
                            TranR, ConvE ,DistMult, DL2vec, OWL2vc)
                            [required]
  -dir, --outdir TEXT       Path to the output directory
  -o, --outfile TEXT        Path to the results output file
  --help                    Show this message and exit.

• Example: embedpvp -d data/ -i example_annotation.vcf.hg38_multianno.txt -p example_cadd.tsv.gz -hpo HP:0004791,HP:0002020,HP:0100580,HP:0001428,HP:0011459 -m hp -e TransE -dir output/ -o example_output1.tsv

Output:

The script will output a ranking a score for the candidate caustive list of variants.
