SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires hail, and includes scripts (resource) components.

What problem does it solve?

This Skill addresses the challenge of interpreting the functional impact of non-synonymous single nucleotide variants by aggregating diverse prediction scores and population frequencies into a unified, queryable format.

Core Features & Use Cases

  • Unified Annotation: Integrates scores from tools like SIFT, PolyPhen-2, CADD, and REVEL alongside gnomAD and 1000 Genomes frequencies.
  • Transcript-Specific Parsing: Automatically organizes transcript-specific scores into structured dictionaries keyed by Ensembl ID.
  • Use Case: Researchers can use this to rapidly filter variants in a large cohort by pathogenicity rankscores, ensuring that only high-confidence, non-circularly trained predictors are prioritized for downstream analysis.

Quick Start

Use the dbnsfp skill to build a variant annotation table from the provided raw input file using the default GRCh38 reference genome.

FAQPage Schema
How do I annotate non-synonymous SNVs with functional prediction scores?

Annotate non-synonymous SNVs by integrating functional prediction scores and population frequency data into a structured Hail Table, normalizing predictor scores to support large-scale genomic variant interpretation workflows.

What is the best way to structure transcript-specific pathogenicity scores for variant filtering?

Structuring transcript-specific pathogenicity scores involves automatically organizing metrics into structured dictionaries keyed by Ensembl transcript ID, allowing researchers to rapidly filter variants in a large cohort by rank-normalized pathogenicity.

Can I use Hail to aggregate SIFT, PolyPhen-2, and REVEL scores for cohort variant interpretation?

Yes, you can use Hail to unify functional prediction scores from tools like SIFT, PolyPhen-2, and REVEL alongside gnomAD and 1000 Genomes population frequencies into one queryable Hail Table for high-performance variant interpretation.

Does this variant annotation approach support the GRCh38 reference genome for large-scale genomic workflows?

Yes, this variant annotation approach supports the GRCh38 reference genome, enabling researchers to build normalized annotation tables from raw input files for large-scale genomic variant interpretation workflows.

Why prioritize non-circularly trained pathogenicity predictors in variant annotation?

Prioritizing non-circularly trained pathogenicity predictors in variant annotation ensures that only high-confidence scores are used for downstream analysis, preventing artificially inflated performance metrics during cohort variant filtering.

How do I normalize functional predictor scores for single nucleotide variants in a Hail Table?

Normalize functional predictor scores for single nucleotide variants by processing raw prediction metrics into standardized rank-normalized pathogenicity metrics within a structured Hail Table for consistent large-scale variant annotation.
