Summary: Epidermolysis bullosa (EB) is a heritable skin disease characterized by marked fragility of epithelialized tissue with blistering in skin and mucous membranes following the slightest mechanical trauma. Eighty percent of all patients suffering from recessive dystrophic EB (RDEB), a subtype originating from mutations in the COL7A1 gene, develop squamous cell carcinoma (SCC). In RDEB patients SCC pre...

Summary: This study seeks to correlate microbiome sequencing data with information provided by patients and their medical records.

Summary: The investigators hypothesize that palmar injections of botulinic toxin, via an inhibition of the sudation, would limit the occurrence of blisters in localized epidermolysis bullosa simplex (LEBS).

Summary: Cockayne syndrome (CS) is related to defective DNA transcription and/or repair and belongs to the family of Nucleotide Excision Repair. It is an autosomal recessive multisystemic disorder characterized by mental retardation, microcephaly, severe growth failure with lipoatrophia, sensorial impairment, cutaneous photosensitivity, dental decay, enophtalmios. The disease is progressive causing severe ...

Summary: The Myelin Disorders Biorepository Project (MDBP) seeks to collect and analyze clinical data and biological samples from leukodystrophy patients worldwide to support ongoing and future research projects. The MDBP is one of the world's largest leukodystrophy biorepositories, having enrolled nearly 2,000 affected individuals since it was launched over a decade ago.Researchers working in the biorepos...

Summary: The primary objective of the study is to determine the safety and feasibility of intrathecal administration of DUOC-01 as an adjunctive therapy in patients with inborn errors of metabolism who have evidence of early demyelinating disease in the central nervous system (CNS) who are undergoing standard treatment with unrelated umbilical cord blood transplantation (UCBT). The secondary objective of t...

Summary: The purpose of this study is to understand the course of rare genetic disorders that affect the brain. This data is being analyzed to gain a better understanding of the progression of the rare neurodegenerative disorders and the effects of interventions.

Summary: Simons Searchlight collects medical, behavioral, learning, and developmental information from people who have gene changes that are linked to autism and other neurodevelopmental disorders. The goal of this study is to improve the clinical care and treatment for these people. Simons Searchlight partners with families to collect data and distribute it to qualified researchers.

Summary: CoRDS, or the Coordination of Rare Diseases at Sanford, is based at Sanford Research in Sioux Falls, South Dakota. It provides researchers with a centralized, international patient registry for all rare diseases. This program allows patients and researchers to connect as easily as possible to help advance treatments and cures for rare diseases. The CoRDS team works with patient advocacy groups, in...

Summary: Four rare genetic diseases, xeroderma pigmentosum (XP), Cockayne syndrome (CS), the XP/CS complex and trichothiodystrophy (TTD) have defective DNA excision repair although only XP has increased cancer susceptibility. We plan to perform careful clinical examination of selected patients with XP, XP/CS, CS, or TTD and follow their clinical course. We will obtain tissue (skin, blood, hair, buccal swab...
