NCT03143374
The purpose of this study is to measure the amount of a protein in the brain known as tau using an imaging procedure called Positron Emission Tomography (PET/CT). Tau has been shown to build up in the brains of patients with injury to brain cells. This study looks at neurodegenerative diseases such as frontotemporal degeneration (FTD).
NCT01148550
The specific aims of this study are (1) to determine the clinical phenotypes and natural history of hepatic RC and FAO disorders, (2) to determine the correlation between genotype and phenotype, (3) to determine if circulating biomarkers reflect diagnosis and predict liver disease progression and survival with the native liver, (4) to determine the clinical outcome of these disorders following liver transplantation, and (5) to develop a repository of serum, plasma, urine, tissue and DNA specimens that will be used in ancillary studies. To accomplish these aims, the ChiLDReN investigators at clinical sites (currently 9 sites) will prospectively collect defined data and specimens in a uniform fashion at fixed intervals in a relatively large number of subjects. Clinical information collected from subjects and their parents will enhance the potential for meaningful research in these disorders. A biobank of previously collected subject specimens and DNA samples will be established for use in ancillary studies to be performed in addition to this study.
