The Cavitron Ultrasonic Surgical Aspirator is a unique modality for precise tissue removal which results in increased visibility, reduced bleeding, and shorter operating time when dealing with vascular lesions or organs.
Mutations in the gene for the enzymes superoxide dismutase 1 (SOD1) or copper zinc superoxide dismutase have been found in approximately 15-20 percent of the familial cases of ALS. Some quick math shows, then, that approximately 1 to 2 percent of all cases of ALS involve this particular gene mutation.
Answer Wiki. , I am a PALS (Person(s) with ALS), Dx 2005. ALS has now several known genetic causes, including mutations in the genes encoding ubiquitous proteins such as SOD1 and TDP43. The largest number known are apparently in a gene called C9orf72, encoding a protein of the same name.
