Summary
A novel human leukocyte antigen (HLA) allele, B*39:60, has been identified. This new HLA allele differs from B*39:01:01 by a single nucleotide substitution.
Area of Science:
- Immunogenetics
- Molecular biology
- Human leukocyte antigen (HLA) system
Background:
- The human leukocyte antigen (HLA) system plays a critical role in immune responses.
- Accurate HLA typing is essential for transplantation and disease association studies.
- Continuous discovery of novel HLA alleles expands our understanding of immune diversity.
Purpose of the Study:
- To report the identification and initial characterization of a new HLA-B allele.
- To contribute to the comprehensive cataloging of HLA polymorphism.
Main Methods:
- Nucleotide sequencing of HLA-B gene.
- Comparison of novel sequence with existing HLA allele databases.
Main Results:
- A novel HLA-B allele, designated B*39:60, was identified.
- B*39:60 differs from the known allele B*39:01:01 by a single nucleotide change at codon 152 (GTG to GCG).
Conclusions:
- The discovery of B*39:60 highlights the ongoing genetic variation within the HLA-B locus.
- This finding adds to the complexity of HLA allele databases and has implications for high-resolution HLA typing.

02:20Blood Types
Human blood is classified into different types based on the presence of antigens on the red blood cell's surface and antibodies in the plasma. Proper identification of blood type is essential for successful blood transfusion. The International Society of Blood Transfusion has identified 38 human blood types based on the surface antigens on the red blood cells. The most common types are ABO, Rh, and MNS blood types.

03:18Non-LTR Retrotransposons
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...
