The pedigree tool: web-based visualization of a family tree

Area of Science:

• Genetics
• Bioinformatics
• Computational Biology

Background:

• Pedigree analysis is crucial for understanding Mendelian and complex trait inheritance.
• Existing tools may lack flexibility in representing diverse genetic features and family structures.
• Efficient data storage and standardized presentation are vital for large-scale genetic studies.

Purpose of the Study:

• To introduce a novel, web-based tool for the design and visualization of pedigrees.
• To develop a flexible notation system capable of representing multiple generations and genetic features.
• To enhance the efficiency of pedigree data storage and standardization for genetic analysis.

Main Methods:

• Development of a Java-programmed, web-based application with a PHP interface.
• Implementation of a unique notation system for comprehensive pedigree data representation.
• Integration with a database of thyroid-stimulating hormone receptor (TSHR) mutations.

Main Results:

• The tool facilitates the generation, editing, and viewing of pedigrees.
• The novel notation supports any number of generations and family members, including multiple clinical/genetic features.
• Significant storage space minimization (100%-500%) and standardized presentation of family trees were achieved.

Conclusions:

• The developed pedigree tool offers a flexible and efficient solution for genetic research.
• It standardizes the presentation of family trees, improving segregation analysis for various disorders.
• The tool's implementation with the TSHR mutation database demonstrates its practical utility.
