EnsemblMap Convert Coordinates

Convert genomic coordinates between human genome assemblies (e.g., GRCh37/hg19 to GRCh38/hg38 or vice versa). Essential for migrating variant positions, GWAS loci, or BED intervals between assembly versions. Uses the Ensembl REST API assembly mapping endpoint. Example: converting BRAF V600E position chr7:140453136 from GRCh37 maps to chr7:140753336 in GRCh38. Supports any species with multiple assemblies.
