Immunoglobulin locus explorer

Reading the map

This page is intentionally a curated teaching map rather than a genome-build-specific browser. Segment order, family color, recombination logic, and constant-region isotype order are emphasized; exact coordinates should be checked against IMGT, OGRDB, NCBI, Ensembl, or a strain-specific assembly before primer design or clinical interpretation.

Sources consulted while building the schematic: IMGT nomenclature concepts, HGNC/NCBI locus naming, and standard immunology descriptions of V(D)J recombination, junctional P/N addition, and class-switch region order.
