Summary
Identifying genes for atopic dermatitis (AD) is crucial for understanding its causes and improving treatments. Current research uses linkage and candidate gene studies to pinpoint genetic factors contributing to AD susceptibility.
Area of Science:
- Genetics
- Dermatology
- Immunology
Background:
- Atopic dermatitis (AD) is a complex genetic disorder.
- Environmental factors also play a role in AD.
- The exact mode of inheritance and involved genes remain unclear.
Purpose of the Study:
- To review current progress in identifying disease-susceptibility genes for AD.
- To summarize findings from linkage and candidate gene studies.
Main Methods:
- Genome-wide and candidate region linkage studies were performed.
- Association studies investigated numerous candidate genes.
- Replicated findings were identified for specific genes like IL-4 and IL-13.
Main Results:
- Multiple AD susceptibility loci identified on chromosomes 3q, 17q, 5q, 11q, and 13q.
- Over 28 candidate genes have been studied.
- Genes including IL-4, IL-13, IL-4RA, mast cell chymase, and serine protease inhibitor, kazal-type 5 showed replicated associations.
Conclusions:
- Identifying AD susceptibility genes aids in understanding pathophysiology and predicting therapy response.
- This knowledge is vital for pharmacogenetics in AD treatment.
- Environmental triggers must be considered for a complete understanding of AD.

01:39Epistasis
In addition to multiple alleles at the same locus influencing traits, numerous genes or alleles at different locations may interact and influence phenotypes in a phenomenon called epistasis. For example, rabbit fur can be black or brown depending on whether the animal is homozygous dominant or heterozygous at a TYRP1 locus. However, if the rabbit is also homozygous recessive at a locus on the tyrosinase gene (TYR), it will have an unshaded coat that appears white, regardless of its TYRP1...
01:28Human Genetics
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.

01:43Incomplete Dominance
Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.
01:28Asthma I: Introduction
Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...
01:18Polygenic Traits
When more than one gene is responsible for a given phenotype, the trait is considered polygenic. Human height is a polygenic trait. Studies have uncovered hundreds of loci that influence height, and there are believed to be many more. Due to the high number of genes involved, as well as environmental and nutritional factors, height varies significantly within a given population. The distribution of height forms a bell-shaped curve, with relatively few individuals in the population at the...
