Table 1 Chromosomal bands smaller than 1.0 Mb in size, according to UCSC Genome Browser (GRCh38/hg38) assembly are listed and compared to the size calculated based on ISCN (2020) idiograms (see Additional file 1: Table 1)

From: About classical molecular genetics, cytogenetic and molecular cytogenetic data not considered by Genome Reference Consortium and thus not included in genome browsers like UCSC, Ensembl or NCBI
