Incomplete Dominance

Incomplete 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.

Cystic Fibrosis: Pathogenesis

Cystic Fibrosis: Pathogenesis

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Genome-wide Association Studies-GWAS

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

The JAK-STAT Signaling Pathway

The JAK-STAT Signaling Pathway

Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...

Area of Science:

Immunology
Genetics
Epidemiology

Background:

Familial clustering and clinical observations suggest a genetic basis for sarcoidosis.
Understanding sarcoidosis genetics is crucial for elucidating disease etiology.

Purpose of the Study:

To review recent advancements in sarcoidosis genetics.
To discuss the role of genetic predisposition in sarcoidosis development.
To highlight how identifying risk alleles can advance understanding of disease mechanisms.

Main Methods:

Review of recent genetic studies on sarcoidosis phenotypes.
Analysis of gene-environment interaction studies.
Examination of heritability estimates from family studies.
Application of whole-exome sequencing.
Gene expression studies of immune cells.

Main Results:

Novel and ancestry-specific genetic associations for sarcoidosis phenotypes identified.
Gene-environment interactions are important for sarcoidosis risk.
Heritability of sarcoidosis is estimated at 49%, indicating other contributing factors.
Whole-exome sequencing linked genetic variants to disease activity and prognosis.
Shared and distinct immune cell pathways identified between sarcoidosis and other granulomatous diseases.

Conclusions:

Sarcoidosis genetic research has identified numerous associations with the disease and its phenotypes.
Emerging sequencing technologies will likely uncover more sarcoidosis-associated genetic variants.
Focusing on phenotypically and ethnically homogeneous patient groups remains essential for genetic research.
