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.
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.
The disease remains progressive and fatal. [11] [12] Patients are managed according to what areas of the body are affected at a particular time. Enzymes, amino acids, antioxidants and vitamins have been used. Treatment for MELAS currently is 1. support the good mitochondria that is left with a mito cocktail and 2. avoid known mito toxins.
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.
While the disease manifests early in life in most cases, diagnosis of the disease is often quite delayed. [ 2 ] [ 4 ] [ 5 ] The symptoms that affected patients present vary, but the most common presenting symptoms are gastrointestinal issues such as nausea, vomiting, abdominal pain, and diarrhea, and neurologic or ocular symptoms such as ...
These diseases can be inherited or acquired by other disorders, drugs, or toxins. Mutations in genes encoding ion channels, which impair channel function, are the most common cause of channelopathies. [1] There are more than 400 genes that encode ion channels, found in all human cell types and are involved in almost all physiological processes. [2]
Cell damage (also known as cell injury) is a variety of changes of stress that a cell suffers due to external as well as internal environmental changes. Amongst other causes, this can be due to physical, chemical, infectious, biological, nutritional or immunological factors.
