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.
What we do know is that in about 2 in 10 families with ALS, the disease is caused by a change in the superoxide dismutase, or SOD1, gene. Genetic changes in genes such as FUS and TDP-43 are the cause of ALS in an even smaller number of families with ALS, each accounting for approximately 1 in 20-25 families.
