Summary
Genetic variants influence COVID-19 severity and cytokine storm. Understanding the genetic basis of coronavirus disease 2019 (COVID-19) aids early detection and intervention.
Area of Science:
- Immunology
- Genetics
- Infectious Diseases
Background:
- Coronavirus disease 2019 (COVID-19), caused by SARS-CoV-2, presents with varied severity.
- Severe cases involve cytokine storm, multi-organ failure, and mortality.
- Risk factors include male gender, advanced age, comorbidities, and potentially genetic factors.
Approach:
- This review synthesizes current knowledge on immune responses to SARS-CoV-2.
- It highlights genetic variants associated with COVID-19 severity and cytokine storm.
- Focuses on immune genes like TLR7 and UNC13D identified in severe cases.
Key Points:
- Genetic defects may contribute to severe COVID-19 and cytokine storm.
- Specific genetic variants in immune response genes are linked to disease severity.
- Immune response mechanisms to SARS-CoV-2 are complex and influenced by host genetics.
Conclusions:
- Investigating the genetic underpinnings of COVID-19 is crucial.
- Identifying genetic predispositions can inform early disease detection strategies.
- Understanding genetic factors enables personalized intervention approaches for severe COVID-19.

15.6K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

329
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,...

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.
The complex relationship between genetics and psychology is observable through common biological components such...

01:26Factors Affecting the Risk of Infection
12.2K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

01:20COPD: Pathogenesis and Clinical Features
437
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...
