Molecular basis of DEL phenotype in the Indian population - Insights from Next-Generation Sequencing Analysis of two cases

The DEL phenotype represents an intriguing and challenging aspect of blood group serology. This condition is characterized by an extremely weak expression of the D antigen on red blood cells, to the extent that it often eludes detection through routine serological methods. Identifying the DEL phenotype necessitates more specialized techniques, such as adsorption and elution tests, to reveal the presence of the D antigen. This distinctive phenotype underscores the complexity and subtlety of blood group genetics and highlights the importance of using advanced methods to accurately classify individuals with this condition, as their ability to form anti-D antibodies can have clinical implications during transfusion and pregnancy scenarios.
