Summary
This study compares Rhesus (Rh) blood group genotyping from different tissues with phenotypes. Most results were concordant, aiding in understanding Rh blood group system variations.
Area of Science:
- Immunology
- Genetics
- Hematology
Background:
- The Rhesus (Rh) blood group system is clinically significant, second only to ABO.
- Rh alloantibodies are a primary cause of hemolytic disease of the newborn (HDN) and transfusion reactions.
Purpose of the Study:
- To explore novel methods for Rh blood group genotyping.
- To compare Rh genotypes identified from various tissues with Rh phenotypes.
Main Methods:
- Utilized Polymerase Chain Reaction (PCR) based methods for RhD, C/c, and E/e genotyping.
- Compared genotypic results with serologically identified phenotypes in 32 individuals.
- Investigated two family members with unusual Rh serotypes.
Main Results:
- Genotyping and phenotyping results showed concordance in most cases (N=32).
- Two family members exhibited unexpected Rh serotypes, deviating from Mendelian inheritance patterns.
- These family members were suspected of having a chromosomal deletion at the RH gene locus.
Conclusions:
- PCR-based Rh genotyping is a reliable method for determining blood group phenotypes.
- Genotyping can identify rare or complex Rh antigen variations, such as chromosomal deletions.
- Further investigation into genetic variations of the Rh gene locus is warranted.
