Recent Advances in Experimental Whole Genome Haplotyping Methods

Area of Science:

• Genomics and Bioinformatics
• Molecular Biology

Background:

• Haplotypes are crucial for understanding genetic variation and disease.
• Current sequencing technologies struggle to directly resolve haplotype information.
• Previous reviews covered early haplotype phasing methods.

Purpose of the Study:

• To review recent experimental methods for haplotype phasing.
• To categorize these methods based on contiguity scale.
• To compare the advantages and disadvantages of different approaches.

Main Methods:

• Review of experimental techniques developed in the last five years.
• Categorization into five classes: encapsulation, 3D structure capture, compartmentalization, fluorography, and long-read sequencing.
• Discussion of specific method instances within each class.

Main Results:

• Emergence of novel experimental methods significantly improving haplotype phasing.
• Categorization provides a framework for understanding diverse approaches.
• Comparative analysis highlights relative strengths and weaknesses of each method class.

Conclusions:

• Recent experimental methods offer substantial improvements in haplotype phasing.
• The reviewed methods provide diverse strategies for resolving genetic variation.
• Understanding these methods aids in selecting appropriate techniques for specific research needs.
