Immunodeficiency Diseases

1.3K
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...

Mismatch Repair01:20

Mismatch Repair

5.4K
Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.
The Mutator Protein Family Plays a Key Role in DNA Mismatch Repair
The human genome has more than 3 billion base pairs of DNA per cell. Prior to cell division, that vast amount of genetic...

Exon Recombination02:32

Exon Recombination

3.7K
The evolution of new genes is critical for speciation. Exon recombination, also known as exon shuffling or domain shuffling, is an important means of new gene formation. It is observed across vertebrates, invertebrates, and in some plants such as potatoes and sunflowers. During exon recombination, exons from the same or different genes recombine and produce new exon-intron combinations, which might evolve into new genes. 
Exon shuffling follows “splice frame rules.” Each exon...

Area of Science:

  • Genetics
  • Immunology
  • Molecular Biology

Background:

  • Reversion mosaicism, involving genetic changes allowing cells to regain wild-type function, is increasingly recognized in genetic disorders.
  • Mechanisms include back mutations, second-site mutations, recombination, deletions, and copy-neutral loss of heterozygosity.

Purpose of the Study:

  • To review recent findings on reversion mosaicism in primary immunodeficiency diseases.
  • To discuss the clinical implications of this phenomenon.

Main Methods:

  • Literature review of studies reporting reversion mosaicism in primary immunodeficiency diseases.
  • Analysis of genetic mechanisms underlying somatic reversion.
  • Evaluation of clinical phenotypes associated with revertant cells.

Main Results:

  • Reversion mosaicism is frequent in primary immunodeficiency diseases, with diverse genetic alterations observed within individuals.
  • Revertant cells can lead to milder disease phenotypes or immune dysregulation.
  • The study of revertant cells provides insights into restored gene function in various cell types.

Conclusions:

  • Reversion mosaicism is a significant factor in the clinical presentation of primary immunodeficiency diseases.
  • Understanding these genetic events is crucial for diagnosing and managing patients.
  • Further research into reversion mosaicism offers therapeutic and biological insights.
