EnsemblLD Get Ld Pairwise

Get pairwise linkage disequilibrium (LD) statistics between two specific variants from the Ensembl REST API. Returns r-squared and D' across ALL 1000 Genomes populations, allowing comparison of LD patterns across ancestries. Useful for assessing whether two GWAS signals are correlated or independent. Example: rs6792369 vs rs1042779 shows r2=1.0 in East Asian populations but r2=0.84 in African populations.
