Ribosomopathies are diseases caused by abnormalities in the structure or function of ribosomal component proteins or rRNA genes, or other genes whose products are involved in ribosome biogenesis. [ 1 ] [ 2 ] [ 3 ]
Mitochondrial disease is a group of disorders caused by mitochondrial dysfunction. Mitochondria are the organelles that generate energy for the cell and are found in every cell of the human body except red blood cells. They convert the energy of food molecules into the ATP that powers most cell functions.
Pearson syndrome is a mitochondrial disease caused by a deletion in mitochondrial DNA (mtDNA). [3] An mtDNA is genetic material contained in the cellular organelle called the mitochondria. Depending on the tissue type, each cell contains hundreds to thousands of mitochondria. There are 2–10 mtDNA molecules in each mitochondrion.
They often cause serious, sometimes fatal, malfunction of several different organ systems (especially the nervous system, muscles, and intestines) in affected infants. [1] The most common sub-type is PMM2-CDG (formerly known as CDG-Ia ) where the genetic defect leads to the loss of phosphomannomutase 2 ( PMM2 ), the enzyme responsible for the ...
The mucopolysaccharidoses are part of the lysosomal storage disease family, a group of genetic disorders that result when the lysosome organelle in animal cells malfunctions. The lysosome can be thought of as the cell's recycling center because it processes unwanted material into other substances that the cell can utilize.
Mitochondrial myopathies are types of myopathies associated with mitochondrial disease. [1] Adenosine triphosphate (), the chemical used to provide energy for the cell, cannot be produced sufficiently by oxidative phosphorylation when the mitochondrion is either damaged or missing necessary enzymes or transport proteins.
What are the neural bases (causes) of mental diseases like psychotic disorders (e.g. mania, schizophrenia), Parkinson's disease, Alzheimer's disease, or addiction? Is it possible to recover loss of sensory or motor function?
Inborn errors of metabolism are often referred to as congenital metabolic diseases or inherited metabolic disorders. [2] Another term used to describe these disorders is "enzymopathies". This term was created following the study of biodynamic enzymology , a science based on the study of the enzymes and their products.
