Pleiotropy01:33

Pleiotropy

44.4K
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...

Single Nucleotide Polymorphisms-SNPs

20.4K
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,...

Comparing Copy Number Variations and SNPs

19.4K
Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...

Non-LTR Retrotransposons03:18

Non-LTR Retrotransposons

14.1K
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...

Induced Pluripotent Stem Cells01:06

Induced Pluripotent Stem Cells

6.4K
Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).

Inflammatory Bowel Disease III: Crohn's Disease

2
Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...

Area of Science:

  • Immunogenetics
  • Allergology
  • Population Genetics

Background:

  • Genetic variants are linked to allergic sensitization, but their specificity and role in poly-sensitization remain unclear.
  • Understanding genetic predispositions is crucial for managing allergic diseases.

Purpose of the Study:

  • To investigate the association between 10 genetic loci and sensitization to specific allergens and poly-sensitization.
  • To identify genetic factors contributing to multiple allergic sensitizations.

Main Methods:

  • Utilized data from the European Community Respiratory Health Survey (ECRHS), a large multicenter population-based study.
  • Assessed associations between 10 genetic loci and specific IgE levels and skin prick test results for individual allergens and poly-sensitization.

Main Results:

  • The 10 studied genetic loci were associated with sensitization to various allergens in a non-specific manner.
  • The C11orf30-rs2155219 locus demonstrated a significant association with poly-sensitization, doubling the risk.
  • This locus showed a correlation with increased C11orf30 gene expression, potentially involved in immune regulation.

Conclusions:

  • The C11orf30-rs2155219 genetic locus plays a significant role in increasing susceptibility to poly-sensitization.
  • This finding suggests C11orf30 is a key genetic factor relevant to the development of atopy.
