EnsemblVEP Annotate Rsid

Predict functional consequences of a genetic variant using its dbSNP rs identifier via the Ensembl Variant Effect Predictor (VEP). Returns impact on genes, transcripts, and proteins including SIFT/PolyPhen scores, consequence types, amino acid changes, and colocated variants. Useful when you have a variant's rs number from GWAS, clinical reports, or literature. Example: 'rs7903146' (TCF7L2 T2D variant), 'rs429358' (APOE Alzheimer variant).
