Features

HmtNote is a bioinformatics tool that can be used to annotate human mitochondrial variants from a VCF, using data available on HmtVar.

Annotations are grouped into basic, cross-reference, variability and predictions, depending on the type of information they provide.

Basic

Basic information about the variant; they include:

• Locus: Locus to which the variant belongs

• AaChange: Aminoacidic change determined

• Pathogenicity: Pathogenicity predicted by HmtVar

• Disease Score: Disease score calculated by HmtVar

Cross-reference

Cross-reference information about the variant; they include:

• Clinvar: Clinvar ID of the variant

• dbSNP: dbSNP ID of the variant

• OMIM: OMIM ID of the variant

• MitomapAssociatedDiseases: Diseases associated to the variant according to Mitomap

• MitomapSomaticMutations: Diseases associated to the variant according to Mitomap Somatic Mutations

Variability

Variability and allele frequency data about the variant; they include:

• NtVarH: Nucleotide variability of the position in healthy individuals

• NtVarP: Nucleotide variability of the position in patient individuals

• AaVarH: Aminoacid variability of the position in healthy individuals

• AaVarP: Aminoacid variability of the position in patient individuals

• AlleleFreqH: Allele frequency of the variant in healthy individuals overall

• AlleleFreqP: Allele frequency of the variant in patient individuals overall

• AlleleFreqH_AF: Allele frequency of the variant in healthy individuals from Africa

• AlleleFreqP_AF: Allele frequency of the variant in patient individuals from Africa

• AlleleFreqH_AM: Allele frequency of the variant in healthy individuals from America

• AlleleFreqP_AM: Allele frequency of the variant in patient individuals from America

• AlleleFreqH_AS: Allele frequency of the variant in healthy individuals from Asia

• AlleleFreqP_AS: Allele frequency of the variant in patient individuals from Asia

• AlleleFreqH_EU: Allele frequency of the variant in healthy individuals from Europe

• AlleleFreqP_EU: Allele frequency of the variant in patient individuals from Europe

• AlleleFreqH_OC: Allele frequency of the variant in healthy individuals from Oceania

• AlleleFreqP_OC: Allele frequency of the variant in patient individuals from Oceania

Predictions

Pathogenicity prediction information of the variant from external resources; they include:

• MutPred_Prediction: Pathogenicity prediction offered by MutPred

• MutPred_Probability: Confidence of the pathogenicity prediction offered by MutPred

• Panther_Prediction: Pathogenicity prediction offered by Panther

• Panther_Probability: Confidence of the pathogenicity prediction offered by Panther

• PhDSNP_Prediction: Pathogenicity prediction offered by PhD SNP

• PhDSNP_Probability: Confidence of the pathogenicity prediction offered by PhD SNP

• SNPsGO_Prediction: Pathogenicity prediction offered by SNPs & GO

• SNPsGO_Probability: Confidence of the pathogenicity prediction offered by SNPs & GO

• Polyphen2HumDiv_Prediction: Pathogenicity prediction offered by Polyphen2 HumDiv

• Polyphen2HumDiv_Probability: Confidence of the pathogenicity prediction offered by Polyphen2 HumDiv

• Polyphen2HumVar_Prediction: Pathogenicity prediction offered by Polyphen2 HumVar

• Polyphen2HumVar_Probability: Confidence of the pathogenicity prediction offered by Polyphen2 HumVar

Usage

Command Line Interface

HmtNote can be used as a command line tool, by simply providing the original VCF and the filename where the annotated VCF will be saved:

hmtnote input_vcf.vcf annotated_vcf.vcf

By default, HmtNote will annotate the VCF using all four groups of annotations (basic, cross-reference, variability and predictions). If desired, you can specify which kind of annotation you want, using respectively --basic, --crossref, --variab and --predict:

hmtnote input_vcf.vcf annotated_basic_vcf.vcf --basic
hmtnote input_vcf.vcf annotated_crossreferences_vcf.vcf --crossref
hmtnote input_vcf.vcf annotated_variability_vcf.vcf --variability
hmtnote input_vcf.vcf annotated_predictions_vcf.vcf --predict

Python Module

HmtNote can also be imported in a Python script and its function annotate_vcf() can be used to annotated a given VCF:

from hmtnote import annotate_vcf
annotate_vcf("input_vcf.vcf", "annotated_vcf.vcf")

By default, annotate_vcf() will annotate the VCF using all four groups of annotations (basic, cross-reference, variability and predictions). If desired, you can specify which kind of annotation you want, using respectively the basic=True, crossref=True, variab=True, predict=True arguments:

annotate_vcf("input_vcf.vcf", "annotated_basic_vcf.vcf", basic=True)
annotate_vcf("input_vcf.vcf", "annotated_crossreferences_vcf.vcf", crossref=True)
annotate_vcf("input_vcf.vcf", "annotated_variability_vcf.vcf", variab=True)
annotate_vcf("input_vcf.vcf", "annotated_predictions_vcf.vcf", predict=True)

Installation

HmtNote can be installed using pip:

$ pip install hmtnote

If you have issues, please refer to the Installation section of the Documentation.
