Background:

TP53 gene mutations are prevalent across numerous human cancers.
Analyzing TP53 mutation patterns across different cancer types can offer insights into disease progression.
Several TP53 mutation databases have been established, with the IARC database being the most comprehensive.

Purpose of the Study:

To describe recent enhancements to the IARC TP53 mutation database.
To introduce a new patient-centered structure and an online analysis tool.
To provide guidance on database utilization and limitations.

Main Methods:

Compilation of all reported TP53 mutations (somatic and inherited) and polymorphisms since 1989 from published literature.
Restructuring the database to be patient-centered with enhanced annotations (carcinogen exposure, virus infection, genetic background).

Main Results:

The IARC TP53 mutation dataset is the largest available for any human gene.
The database now offers a more detailed, patient-focused view of TP53 variations.
A functional online tool is available for querying and analyzing somatic mutation data.

Conclusions:

The updated IARC TP53 database provides a valuable resource for cancer research.
The new features facilitate deeper analysis of TP53 mutation patterns and their relation to patient factors.
Recommendations for effective database use are provided to researchers.
