clinvar-database

Query ClinVar variants by gene, condition, or genomic location using NCBI E-utilities like esearch and esummary. Filter pathogenicity records by interpreting CLNSIG classifications and review status star ratings to identify the most reliable results for your research.

Annotate VCF files with ClinVar pathogenicity data by downloading bulk ClinVar datasets in VCF format. Filter and annotate variant call sets using tools like bcftools to parse tab-delimited data or XML for downstream genomic analysis.

ClinVar review status uses star ratings to indicate the level of assertion confidence. Translate CLNSIG values and review statuses into actionable filtering logic, applying conflict-aware handling for submissions with differing pathogenicity interpretations or VUS classifications.

Retrieve bulk ClinVar datasets in XML format using NCBI E-utilities such as efetch and elink, or via FTP bulk downloads. Parse the XML or tab-delimited files to extract variant evidence while tracking genome build and review status for accurate interpretation.

Handle conflicting pathogenicity submissions in ClinVar variants by applying conflict-aware logic during interpretation. Evaluate clinical significance and review confidence statuses together to filter VUS and conflicting records effectively for genomic annotation workflows.

Specify the genome build when parsing ClinVar XML or VCF bulk data to ensure accurate genomic coordinate mapping. Tracking the genome build alongside review status during bulk dataset processing prevents alignment errors in variant annotation workflows.
