TY - JOUR T1 - NEw model system offers clues to als AU - Kuehn BM Y1 - 2011/10/12 N1 - 10.1001/jama.2011.1439 JO - JAMA SP - 1534 EP - 1534 VL - 306 IS - 14 N2 - ALS is a progressive and ultimately fatal disorder in which the motor neurons in a patient's central nervous system die off, causing paralysis and eventually respiratory failure. Most cases are sporadic, but about 20% are linked to mutations in the superoxide dismutase 1 (SOD1) gene. However, scientists have so far been unable to identify the precise mechanisms behind the motor neuron loss.
