        "note": "dbVar is NCBI's archive of human genomic structural variation — structural variants (SVs) larger than ~50 bp: copy-number variants (CNVs), large deletions and duplications, insertions, inversions and translocations. /v1/search?gene=BRCA1 finds structural variants overlapping a gene (or use q= for free-text), returning each variant's dbVar accession (e.g. nsv7897183), the study it came from, variant type, organism, overlapping genes, GRCh38 genomic placement and clinical significance; /v1/variant?id=nsv7897183 returns a single variant's full record — placements on all assemblies (GRCh37 and GRCh38), variant type, genes, clinical significance, study type, methods and variant counts (you may also pass the numeric uid). Accessions look like nsv… (variant), nssv… (variant call) or nstd… (study). Data from NCBI dbVar (public domain). A structural-variation / CNV resource — distinct from clinical single-nucleotide variant interpretation (ClinVar), population allele frequencies (gnomAD) and trait associations (GWAS). Ideal for genomics, cytogenetics, rare-disease and bioinformatics tools.",
