Insights

Mitochondrial respiratory chain disorders are common in children, with a higher prevalence (1/9,000 births) than previously thought. This study highlights their varied presentations and increased occurrence in specific populations.

Area of Science:

  • Pediatric Medicine
  • Genetics
  • Neurology

Background:

  • Mitochondrial respiratory chain disorders present diverse clinical features in children.
  • Accurate prevalence data for pediatric mitochondrial diseases are lacking, with potential geographic variations.
  • These disorders significantly impact pediatric healthcare and require better epidemiological understanding.

Purpose of the Study:

  • To determine the prevalence of mitochondrial respiratory chain disorders in a specific pediatric population.
  • To analyze the clinical features associated with these disorders.
  • To investigate potential contributing factors to prevalence, such as consanguinity.

Main Methods:

  • Retrospective analysis of pediatric cases over a seven-year period.
  • Data collected from a tertiary care center.
  • Inclusion of clinical features and population demographics.

Main Results:

  • The study identified a higher than expected prevalence of mitochondrial disorders (1 in 9,000 births).
  • Consanguinity within the Irish Traveller subgroup contributed to a higher incidence in this population.
  • Varied clinical presentations were observed across affected children.

Conclusions:

  • Mitochondrial respiratory chain disorders are more prevalent in the pediatric population than previously estimated.
  • Consanguinity plays a role in the increased prevalence observed in specific subgroups.
  • Further research is needed to understand the full scope and geographic distribution of these disorders.

Animal Mitochondrial Genetics

Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...
Mitochondrial Membranes01:45

Mitochondrial Membranes

A single mitochondrion is a bean-shaped organelle enclosed by a double-membrane system. The outer membrane of mitochondria is smooth and contains many porins - the integral membrane transporters. Porins enable free diffusion of ions and small uncharged molecules through the outer mitochondrial membrane but limit the transport of molecules larger than 5000 Daltons. Further, the outer mitochondrial membrane forms a unique structure called membrane contact sites with other subcellular organelles,...

Mitochondrial Precursor Proteins01:39

Mitochondrial Precursor Proteins

Mitochondrial precursors are partially unfolded or loosely folded polypeptide chains. Newly synthesized precursors are inhibited from spontaneously folding into their native conformation by the cytosolic chaperones, heat shock proteins 70 (Hsp70), and mitochondrial import stimulation factors (MSFs). Precursors bound to MSFs are guided to the TOM70-TOM37 receptors, while precursors bound to Hsp70  chaperones are targetted to TOM20-TOM22 receptor complexes.
Most of the mitochondrial precursors...
Mitochondrial Protein Sorting01:39

Mitochondrial Protein Sorting

Mitochondria are double-membrane organelles of the eukaryotes involved in cellular metabolism, signaling, ATP synthesis, and programmed cell death.  Each of these processes requires specific proteins and enzymes that must be correctly sorted to the right mitochondrial subcompartment for the proper functioning of the organelle.
Most of these mitochondrial proteins are encoded by the nucleus and imported to the mitochondria as unfolded or loosely folded precursors. Mitochondrial precursors...

Pharmacogenetics of Phase I Enzymes: Cytochrome P450 Isozymes

Cytochrome P450 (CYP450) enzymes are a superfamily of heme-containing monooxygenases that play a pivotal role in Phase I drug metabolism by catalyzing oxidation and reduction reactions.These enzymes transform lipophilic xenobiotics into more hydrophilic metabolites, facilitating subsequent Phase II conjugation and eventual excretion. The CYP450 family is classified into families (e.g., CYP1–CYP3) and subfamilies (e.g., CYP2A, CYP2C), based on amino acid sequence homology.CYP450 isoenzymes,...
