Background:

Recurrently observed cancer mutations, known as hotspots, are presumed to be functional.
Known hotspots in genes like BRAF, PIK3CA, TP53, KRAS, and IDH1 support this functional hypothesis.
However, numerous potential hotspots remain experimentally unvalidated, and their computational detection is hindered by background mutations.

Purpose of the Study:

To provide a comprehensive review of computational methods for detecting cancer mutation hotspots.
To organize and describe over 40 existing algorithms for hotspot identification in both coding and non-coding DNA.
To discuss the advantages, future directions, and potential applications of these computational methods.

Main Methods:

Categorization of over 40 computational hotspot detection methods into cluster-based, 3D, position-specific, and miscellaneous groups.
Detailed description of the procedures, implementations, variations, and differences among these methods.
Review of existing literature on computational approaches for identifying cancer mutation hotspots.

Main Results:

A systematic overview and categorization of more than 40 computational tools for cancer hotspot detection.
Identification of challenges in hotspot detection due to background mutations.
Discussion of the strengths and weaknesses of various computational approaches.

Conclusions:

Computational methods are essential for identifying cancer mutation hotspots, despite detection challenges.
This review consolidates existing knowledge and provides a framework for understanding and developing new hotspot detection algorithms.
Future opportunities include applying these methods to viral integrations, translocations, and epigenetic modifications.
