This track displays simple tandem repeats (possibly imperfect repeats) on the 12 Apr 2019 Grammomys surdaster/GCF_004785775.1_NIH_TR_1.0/GCF_004785775.1 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 1,424,025 items in the track covering 77,913,452 bases, assembly size 2,412,664,998 bases, percent coverage % 3.23.
