Summary
Genetic testing for primary immunodeficiency is becoming more accessible and affordable, aiding allergists-immunologists in diagnosing immune disorders. Adopting these advanced genetic tools can lead to more accurate diagnoses and effective patient management.
Area of Science:
- Clinical Immunology
- Medical Genetics
- Allergy Diagnostics
Background:
- Genetic testing is an advanced diagnostic tool for primary immunodeficiency (PID).
- Its integration into daily practice for allergists-immunologists remains a challenge.
- Despite challenges, educational initiatives support its use in PID diagnosis and management.
Purpose of the Study:
- To highlight the increasing accessibility and affordability of genetic testing for PID.
- To encourage the adoption of genetic testing into routine clinical practice.
- To emphasize the benefits of genetic testing in diagnosing and managing immune abnormalities.
Main Methods:
- Utilizing comprehensive genetic testing panels (few to hundreds of genes).
- Employing next-generation sequencing and deletion/duplication assays.
- Considering whole-exome and whole-genome sequencing for undiagnosed cases, with genetic counselor support.
Main Results:
- Genetic testing panels offer high-quality, comprehensive analysis for immune abnormalities.
- Results facilitate accurate diagnosis, effective treatment, and informed patient counseling.
- Testing aids in identifying risks for family members and guiding referrals for specialized care.
Conclusions:
- Genetic testing is a valuable tool for allergists-immunologists to diagnose PID and immune disorders.
- Increased affordability and accessibility should drive its adoption in clinical practice.
- It improves diagnostic accuracy, treatment efficacy, and patient/family understanding of disease etiology.

01:16In-vitro Mutagenesis
To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.

02:46Genetic Screens
Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which result in visible changes...

01:28Human Genetics
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
