Insights

Newly identified mutations in the tetratricopeptide repeat domain 7A (TTC7A) gene were found in an infant with multiple intestinal atresia and combined immunodeficiency, expanding the understanding of this genetic disorder.

Area of Science:

  • Genetics
  • Immunology
  • Pediatric Medicine

Background:

  • Mutations in the tetratricopeptide repeat domain 7A (TTC7A) gene have recently been linked to autosomal recessive disorders.
  • These disorders are characterized by multiple intestinal atresia and severe combined immunodeficiency.

Observation:

  • This study focuses on the clinical progression of an infant diagnosed with multiple intestinal atresia and combined immunodeficiency.
  • The infant was found to carry compound heterozygote mutations in the TTC7A gene.

Findings:

  • The identified mutations in the TTC7A gene are novel, expanding the known mutation spectrum for this gene.
  • This case highlights the role of TTC7A in both intestinal development and immune system function.

Implications:

  • Understanding TTC7A mutations provides insights into the pathogenesis of multiple intestinal atresia and combined immunodeficiency.
  • Further research into TTC7A may lead to improved diagnostics and potential therapeutic strategies for affected individuals.

Immunodeficiency Diseases01:25

Immunodeficiency Diseases

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...

Role Of Notch Signalling In Intestinal Stem Cell Renewal01:12

Role Of Notch Signalling In Intestinal Stem Cell Renewal

Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

Translation01:31

Translation

Lesson: Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.

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,...

Alternative RNA Splicing02:18

Alternative RNA Splicing

Alternative RNA splicing is the regulated splicing of exons and introns to produce different mature mRNAs from a single pre-mRNA. Unlike in constitutive splicing where a single gene produces a single type of mRNA, alternative splicing allows an organism to produce multiple proteins from a single gene and plays an important role in protein diversity.
There are five types of alternative RNA splicing that vary in the ways the pre-mRNA segments are removed or retained in the mature mRNA. The first...
