chromosome sub-band
The descriptor 1p22.3 = chromosome 1, short arm, region 2, band 2, sub-band 3. This is read as "one q two-two point three", not "one q twenty-two point three".
http://ghr.nlm.nih.gov/handbook/howgeneswork/genelocation and http://people.rit.edu/rhrsbi/GeneticsPages/Handouts/ChromosomeNomenclature.pdf, both of which define the nomenclature for the banding hierarchy we use here:
chromosome > arm > region > band > sub-band
Note that an alternate nomenclature for this hierarchy is here (http://www.ncbi.nlm.nih.gov/Class/MLACourse/Original8Hour/Genetics/chrombanding.html):
chromosome > arm > band > sub-band > sub-sub-band
