MaveDB Get Gnomad Variants

Get gnomAD population-frequency variants observed within a MaveDB score set. Returns gnomAD variants with dbIdentifier (e.g. '13-32319097-A-C'), gnomAD version (e.g. 'v4.1'), allele count, allele number, and allele frequency, each linked to the MaveDB mapped variant via a genomic VRS Allele. Cross-reference allele frequency with the measured MAVE functional score: rare variants with strong functional impact are candidate disease alleles. Obtain the URN from MaveDB_search_score_sets.
