Summary
This summary is machine-generated.A novel variant of the HLA-DPA1 gene, specifically HLA-DPA1*01:228, has been identified. This variant features a previously undocumented alanine amino acid at position 42.
Area Of Science
- Immunogenetics
- Molecular biology
- Human leukocyte antigen (HLA) system
Background
- The Human Leukocyte Antigen (HLA) system plays a crucial role in immune response.
- Genetic variations within HLA genes contribute to diverse immune profiles and disease susceptibility.
- Accurate characterization of HLA alleles is essential for transplantation and autoimmune disease research.
Purpose Of The Study
- To report the discovery and characterization of a novel HLA allele.
- To document a previously undescribed amino acid substitution in the HLA-DPA1 gene.
Main Methods
- High-resolution HLA typing techniques were employed.
- Sequence analysis was performed to identify genetic variations.
- Comparison with existing HLA allele databases was conducted.
Main Results
- A new allele, designated HLA-DPA1*01:228, was identified.
- This allele exhibits an alanine at amino acid position 42.
- This specific amino acid substitution at this position has not been previously reported in the HLA-DPA1*01 lineage.
Conclusions
- The discovery of HLA-DPA1*01:228 expands the known diversity of the HLA-DPA1 gene.
- This finding contributes to a more comprehensive understanding of HLA polymorphism.
- The documented alanine at position 42 may have implications for T-cell recognition and immune function.

Agouti: A Lethal Allele
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...
The Concept of Multiple Allelism
Multiple allelism describes genes that exist in three or more allelic forms. Although diploid organisms, like humans, normally possess only two alleles of each gene, there are multiple alleles of many (if not most) human genes present in a population. Blood type is one example of multiple allelism. There are three alleles for blood type (HBB gene) in humans: IA, IB, and i.
