Summary
A new Human Leukocyte Antigen (HLA) allele, HLA-A*66:28N, has been identified. This novel allele is distinguished from HLA-A*66:03 by a single nucleotide deletion.
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 and transplantation.
- Accurate HLA allele identification is essential for clinical applications and population genetics.
Purpose of the Study:
- To report the discovery and characterization of a novel HLA-A allele.
- To detail the specific genetic variation differentiating the new allele from a known one.
Main Methods:
- High-resolution HLA typing methodologies were employed.
- Sequence analysis was performed to identify nucleotide variations.
Main Results:
- A novel HLA allele, designated HLA-A*66:28N, was identified.
- This allele differs from the known HLA-A*66:03 allele by a single nucleotide deletion at codon 185.
Conclusions:
- The identification of HLA-A*66:28N expands the known HLA-A allele repertoire.
- This finding contributes to the understanding of HLA polymorphism and its implications for immune system research.

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...

01:25What is Population Genetics?
64.8K
A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, they pass down their genes to their offspring. Many of these genes are polymorphic, meaning that they occur in multiple variants. Such variations of a gene are referred to as alleles. The collective set of all the alleles within a population is known as the gene pool.

Diploid organisms have two alleles of each gene, one from each parent, in their somatic cells. Therefore, each individual contributes two alleles to the gene pool of the population. The gene pool of a population is the sum of every allele of all genes within that population and has some degree of variation. Genetic variation is typically expressed as a relative frequency, which is the percentage of the total population that has a given allele, genotype or phenotype.

Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
