EVA Get Variants By Gene

Get genetic variants from the European Variation Archive (EVA) for a specific gene. EVA is hosted at EBI and aggregates variant data from multiple studies including ClinVar, dbSNP, and population sequencing projects. Returns variants with allele frequencies, study sources, and variant type. The gene name uses HGNC symbols (e.g., 'BRCA1', 'TP53', 'EGFR'). Species defaults to human GRCh38.
