A new algorithm, HORmon, automatically annotates human centromeres by integrating monomer and higher-order repeat (HOR) inference. This advances studies on centromere evolution and genetic diseases.
Area of Science:
- Genomics
- Molecular Biology
- Bioinformatics
Background:
- Long-read sequencing advances enable detailed studies of human centromere architecture and evolution.
- Centromere annotation, partitioning into monomers and higher-order repeats (HORs), is crucial but lacks automated algorithms.
Purpose of the Study:
- To develop a rigorous, automated algorithm for centromere annotation.
- To integrate monomer and HOR inference into a unified framework for accurate centromere analysis.
Main Methods:
- Developed the HORmon algorithm, integrating monomer and HOR inference.
- Applied the algorithm to automatically generate human monomers and HORs.
Main Results:
- The HORmon algorithm successfully integrates monomer and HOR inference.
- Generated human monomers/HORs largely consistent with previous semi-manual studies.
- Automated annotation is now feasible for centromere-related genetic and evolutionary research.
Conclusions:
- The HORmon algorithm provides a robust solution for automated centromere annotation.
- Integrated inference of monomers and HORs is essential for accurate centromere characterization.
- This work facilitates future research into centromere function, evolution, and associated diseases.

Chromosome Structure
The centromere is a DNA sequence that links sister chromatids. This is also where kinetochores, protein complexes to which spindle microtubules attach, are constructed after the chromosome is replicated. The kinetochores allow the spindle microtubules to move the chromosomes within the cell during cell division.
