  You first need to get the coordinates of the "cytoband" 21q22.11, which I would search for using the [UCSC table browser](https://genome.ucsc.edu/cgi-bin/hgTables?hgsid=791314831_aE2GlksiE79iyiT0FHCRXDZcFwPC). You need the following settings:
  Clade: Mammal
  genome: Human
  assembly:
  group: Mapping and Sequencing
  track: Chromosome Band
  table: cytoBand
  region: position chr21
  output format: BED
  
  (you can leave other options as default)
  
  That will give you a bed file of cytobands on chr21. You'll need to search (e.g. grep) for your cytoband: q22.11.
