This track displays simple tandem repeats (possibly imperfect repeats) on the 02 Jul 2018 Homo sapiens/GCA_002209525.2_HG01352_prelim_2.1/GCA_002209525.2 genome assembly, located by Tandem Repeats Finder (TRF) which is specialized for this purpose. These repeats can occur within coding regions of genes and may be quite polymorphic. Repeat expansions are sometimes associated with specific diseases.

There are 1,011,770 items in the track covering 122,244,006 bases, assembly size 2,884,526,810 bases, percent coverage % 4.24.
