UCSC Get Track

Get annotation track data from the UCSC Genome Browser for a specified genomic region. Retrieves features like genes, regulatory elements, conservation scores, variants, or repeats from any of UCSC's 370+ tracks. Use UCSC_search first to find the genomic coordinates of your gene of interest. Example: track 'knownGene' on hg38 chr17:7668421-7687490 returns GENCODE gene annotations for the TP53 region.
