Amyotrophic Lateral Sclerosis Progressive Muscular Atrophy |
Amyotrophic Lateral Sclerosis (ALS) is a devastating motor neuron disease that typically causes rapidly progressive muscle weakness, disability and premature death. In spite of a large number of attempted ALS trials, there are no significant disease-modifying therapies for this condition to-date.
There exists a small group of patients who meet diagnostic criteria for ALS or progressive muscular atrophy (PMA), progress for a period of time, and then significantly improve. Some of these "ALS reversals" even make a complete recovery back to normal neurological function. The investigator has independently verified 34 of these cases so far through review of medical records and peer-reviewed literature. These patients are different in their demographics and disease characteristics as compared to patients with more typically progressive ALS. One possible explanation for these cases is that these patients are genetically different than most patients with ALS and that these differences confer a form of disease "resistance". Study of these selected reversal patients may yield valuable clues to endogenous mechanisms of ALS resistance. The concept of genetic conferred ability to resist a disease is not novel. A group of patients who could unexpectedly "control" HIV due to a mutant allele has led to an improved understanding of HIV pathophysiology and a new treatment
This is a pilot case-control study attempting to discover genetic correlates to ALS reversals. The investigator will collect demographics, disease characteristics, pedigree information and saliva samples from ALS reversals. Whole genome DNA will be extracted and sequenced from these saliva samples. The genomes of ALS reversals will then be compared with whole genome sequencing previously completed from a biorepository of de-identified samples of more typically progressive patients with ALS. The study will not save any saliva samples collected as a part of this new protocol for future research.

Plan Description: | Information obtained from this analysis (genotypic data), as well as information about disease signs and symptoms (phenotypic data), will be entered into one or more scientific repositories maintained by organizations such as the New York Genome Center (NYGC) and the Federal Government. One such repository is the Database of Genotypes and Phenotypes (dbGaP), a data repository at the NIH. All data and information will be submitted via a secure transmission process to a high security network within NIH. While the information and data resulting from this study may be presented at scientific meetings or published in a scientific journal, your name or other personal information will not be revealed. |
