Background:

Haplotype visualization is crucial for gene mapping.
Mendelian diseases require precise identification of disease-causing genes.
Existing tools may struggle with large, complex haplotype datasets.

Purpose of the Study:

To develop a user-friendly application for visualizing complex haplotype information.
To facilitate gene mapping in Mendelian diseases by defining the smallest critical interval.
To address the need for efficient viewing of large haplotypes from genome scans.

Main Methods:

Developed HaploPainter, a Perl-based pedigree-drawing application.
Integrated features for easy visualization of complex haplotype data.
Included functionalities like haplotype compression and marker section cut-out.

Main Results:

HaploPainter provides user-friendly visualization of complex haplotypes.
The software aids in fast and reliable definition of critical intervals for gene defects.
It efficiently handles large haplotype datasets generated by high-density marker panels, including single nucleotide polymorphisms (SNPs).

Conclusions:

HaploPainter enhances gene mapping efficiency for Mendelian diseases.
The application is valuable for analyzing complex genetic data from genome-wide association studies.
Its features support researchers working with large-scale genetic marker data.
