VIP-HL

VIP-HL provides semi-automated ACMG/AMP variant interpretation tailored to genetic hearing loss to classify sequence variants according to ClinGen hearing loss expert panel (HL-EP) specifications.

Key Features:

• Guideline integration: Implements ACMG/AMP specifications as refined by the ClinGen HL-EP and automates 13 of 24 specified rules: PVS1, PS1, PM1, PM2, PM4, PM5, PP3, BA1, BS1, BS2, BP3, BP4, and BP7.
• Data aggregation: Aggregates evidence from external databases to support automated rule activation and variant interpretation.
• Benchmark concordance (small set): In a benchmarking set of 50 variants with 83 activated rules by the HL expert panel, achieved concordant activation for 96% (80/83) of rules versus 47% (39/83) for InterVar.
• Broad validation: Demonstrated 88.0% overall variant interpretation concordance across 4,948 ClinVar star 2+ variants from 142 deafness-related genes.

Scientific Applications:

• Clinical variant classification for hearing loss: Classifies sequence variants according to ACMG/AMP criteria specified for genetic hearing loss by the ClinGen HL-EP.
• Variant curation and rule activation: Supports systematic activation of evidence-based ACMG/AMP rules for curator use and expert review.
• Benchmarking and validation: Enables comparison of automated rule activations and variant classifications against HL expert panel annotations and tools such as InterVar using ClinVar-derived datasets.

Methodology:

Automates activation of 13 specified ACMG/AMP rules (PVS1, PS1, PM1, PM2, PM4, PM5, PP3, BA1, BS1, BS2, BP3, BP4, BP7), aggregates evidence from external databases, and evaluates concordance against ClinGen HL-EP annotations and InterVar using test sets including 50 variants (83 activated rules) and 4,948 ClinVar star 2+ variants from 142 deafness-related genes.
