A novel technique for NOD2/CARD15 genotyping using PCR-SSP

Area of Science:

• Immunology
• Genetics

Background:

• Nucleotide-binding Oligomerisation Domain (NOD) 2 protein, encoded by the Caspase Recruitment Domain (CARD) 15 gene, is vital for innate immunity.
• Single Nucleotide Polymorphisms (SNPs) in NOD2/CARD15 are associated with Inflammatory Bowel Disorders (e.g., Crohn's Disease, Blau syndrome) and cancer progression.
• NOD2/CARD15 SNPs in donor-recipient pairs predict adverse outcomes in hematopoietic stem cell transplantation, including increased Graft-versus-Host disease, relapse, and mortality.

Purpose of the Study:

• To develop a rapid and accurate method for genotyping specific Single Nucleotide Polymorphisms (SNPs) in the NOD2/CARD15 gene.
• To facilitate the identification of NOD2/CARD15 SNPs implicated in various diseases and transplant complications.

Main Methods:

• Development of a Polymerase Chain Reaction assay using Sequence Specific Primers (PCR-SSP).
• The PCR-SSP assay was designed to specifically identify three implicated NOD2/CARD15 SNPs (SNPs 8, 12, and 13).

Main Results:

• The developed PCR-SSP assay provides a fast and accurate method for NOD2/CARD15 genotyping.
• Performance was validated against existing genotyping techniques, demonstrating superior speed and accuracy.

Conclusions:

• The PCR-SSP assay is an effective tool for rapid and accurate NOD2/CARD15 genotyping.
• This method can aid in predicting disease risk and transplant outcomes by identifying relevant SNPs.
