abstract：:Repeat regions are low-complexity regions in the human genome that largely code for intrinsic disorder in proteins. Expansions outside the normal thresholds in repeat regions are likely to be pathogenic, leading to the so-called repeat expansion diseases. There have been numerous studies on the most common group of re...
