HAP1, a new revolutionary cell model for gene editing using CRISPR-Cas9.

Area of Science:

• Genetics
• Genomics
• Cell Biology

Background:

• Next-generation sequencing (NGS) identifies numerous genetic variants in complex diseases like cancer, but their functional significance remains unclear.
• Haploid human cell models, particularly the HAP1 cell line, are crucial for unmasking variant phenotypes due to their single genome copy.
• CRISPR-Cas9 gene editing technology enables efficient modification of the HAP1 genome.

Purpose of the Study:

• To review the application of the HAP1 cell line with CRISPR-Cas9 for functional genetic studies.
• To explore the development of disease models and understanding the genetic basis of human diseases.
• To highlight the potential for interpreting genetic variants and impacting clinical practice.

Main Methods:

• Utilizing the HAP1 near-haploid cell line for genetic studies.
• Employing CRISPR-Cas9 gene editing for high-throughput genetic screens.
• Analyzing functional gene studies and genetic variant interpretation.

Main Results:

• HAP1 cells facilitate the unmasked phenotypic display of genetic variants.
• CRISPR-Cas9 enables efficient gene editing in HAP1 cells for functional analysis.
