On Jul. 28, 2021, the National Institutes of Health announced that by studying lab-grown neurons derived from skin or blood cells from 10 normal controls, eight with an ALS causing mutation, and 17 with non-inherited ALS, researchers have found a possible starting point for the dysfunction that causes the disease.

The study, which was published in Science Translational Medicine was funded in part by the National Institute for Neurological Disorders and Stroke.
