Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Many of these disorders have a wide spectrum of phenotypic variability. For example, the severity of SMA is quite variable even though it is caused by the loss of a single gene, i.e. survival motor neuron 1 (SMN1). The number of copies of the duplicated gene survival motor neuron 2 (SMN2) dictates phenotypic severity in SMA. In this study, the research team will also identify potential modifiers of phenotypic severity for specific disorders like SMA and Charcot-Marie-Tooth (CMT) disease. With the identification of novel modifier genes, the investigators will be able to more accurately predict disease outcomes and the investigators will also have novel targets for the development of therapeutic agents for these diseases.
