Filter by:This is a single patient study of oral powdered fluoxetine to target developmental outcomes in a child with KCNC1-related disorder. This trial will be conducted at Holland Bloorview Kids Rehabilitation Hospital over 32 to 42 weeks, using a quasi experimental ABA phase design (placebo-fluoxetine-placebo) with randomized and blinded active treatment start and stop moments.
The project is focused on the detailed study of structural genomic variants (SVs). Such genetic mutations are in fact alterations in the DNA molecule structure and include copy number variants, inversions and translocations. A single event may affect many genes as well as regulatory regions and the specific phenotypic consequences will depend on the location, genetic content and type of SV. Many times, the specific disease-causing mechanism is not known. Here, we plan to study the molecular genetic behavior of structural variants as well as the underlying mutational mechanisms involved. First, we will use genome sequencing to pinpoint the chromosomal breakpoints at the nucleotide level, characterize the genomic architecture at the breakpoints and study the relationship between structural variants and SNVs. Second, we will study how structural variants impact gene expression. Finally, we will functionally explore the disease mechanisms in vivo using zebrafish and in vitro using primary patient cells and induced pluripotent stem cells. Our studies will focus on the origin, structure and impact of structural variation on human disease. The results will directly lead to a higher mutation detection rate in genetic diagnostics. Through a better understanding of disease mechanisms our findings will also assist in the development of novel biomarkers and therapeutic strategies for patients with rare genetic disorders.
This research study is being done to find markers and identify causes of rare and undiagnosed diseases by analyzing patient's DNA (i.e., genetic material), RNA, plasma, urine, tissues, or other samples that could be informative of symptoms. Researchers are creating a biobank (library) of samples and information to learn more about treating rare and undiagnosed diseases.
SLC13A5 deficiency (Citrate Transporter Disorder, EIEE 25) is a rare genetic disorder with neurodevelopmental delays and seizure onset in the first few days of life. This natural history study is designed to address the lack of understanding of disease progression and genotype-phenotype correlation. Additionally it will help in identifying clinical endpoints for use in future clinical trials.
We propose to set up a prospective randomized controlled trial to control the security and assess the efficacy of adjuvant treatment by rheopheresis in necrotizing-ulcered calciphylaxis in the hemodialysis population.
This research is being done to learn more about possible genetic causes of currently undiagnosed conditions, and to find out how the development of new technologies, such as DNA sequencing, can increase knowledge of the role genetic variants play in disorders and possibly how genetic variants may help de-termine the best treatment options. The recent development of new technologies has increased our ability to understand how genetic mutations are associated with disease. Using these technologies to find the genetic variants responsible for rare diseases is a rapidly growing field and has already begun to transform the way conditions with unknown causes are diagnosed and treated. Hypothesis: Identification of new genomic variants associated with idiopathic diseases and/or diseases of unknown etiology will advance medical knowledge about rare and common diseases.
Even though rare disorders usually have limited case numbers, they have induced huge impacts on patients and their families, and has heavily burdened on our society and healthcare system as well. Therefore, it is essential to detect the occurrence of disorders and thus take appropriate measures as early as possible. The preventive goal is based on comprehensive understanding on rare disorders, available diagnostic and therapeutic approaches. However, studies related to rare disorders are often impeded by limited sample sizes and infrequent exchange of research materials among institutes. After referring to foreign experiences, the investigators have noticed that a non-profit tissue bank which can reposit biological samples and thus provide researchers access to samples, may be a solution. Through sharing this public asset, the investigators believe not only quantity and quality of rare disorder studies will be improved, the collaboration between various research institutes can also be strengthened afterwards. Most important of all, those achievements can ultimately benefit patients, families and the whole society.
