NCBIVariation Spdi Equivalents

Get all equivalent SPDI representations of a variant across different reference sequences and genome assemblies (GRCh37/GRCh38, RefSeqGene, transcript). Given one SPDI, returns the same variant mapped to all available coordinate systems. Useful for liftover between assemblies and cross-referencing variants described on different reference sequences.
