The protocol aims to comprehensively define the phenotype of Phelan-McDermid Syndrome and to identify potential genetic factors, which may play a role in the variability of the disease's outcomes. The first aim involves a physical exam, a neurological exam, collection...

Ichthyosis is a group of genetic skin disorders that present with dry, thickened, scaly, or flaky skin. As of today, there is no cure or treatment. Doctors can only treat the dry skin with different types of emollients to soften the scale. A deeper understanding of th...

The investigators are collecting genetic information through blood samples as well as clinical and EEG data from over 1000 people with Juvenile Myoclonic Epilepsy (JME) across the UK, Europe and North America. This study will draw on both existing and new samples from...

Vitiligo is a common acquired disorder of pigmentation affecting 0.5% to 1% of the world population. Sharply demarcated patches of depigmentation, which can affect all ethnicities, and can lead to cosmetic disfiguration and psychosocial distress, characterize the diseas...

The ichthyoses are a group of lifelong genetic disorders which share characteristics of generalized skin thickening, scaling and underlying cutaneous inflammation. There are no therapies based on growing understanding of what causes the disease. However, there have been...

Craniosynostosis (CS) is a common malformation occurring in ~4 per 10,000 live births in which the sutures between skull bones close too early, causing long-term problems with brain and skull growth. Infants with CS typically require extensive surgical treatment and may...

This is a prospective, observational, cohort study of patients with a clinical diagnosis of diabetes who are undergoing clinically indicated kidney biopsy. The intent is to collect, process, and study kidney tissue and to harvest blood, urine and genetic materials to ...

Here we propose an "integrative sequencing approach" utilizing a 1500 gene exome comparative analysis between multiple myeloma or related plasma cell malignancies and normal cells coupled to capture transcriptome sequencing to provide a nearly comprehensive landscape ...

Since its launch in 2004, the overarching aim of the Alzheimer's Disease Neuroimaging Initiative (ADNI) has been realized in informing the design of therapeutic trials in AD. ADNI3 continues the previously funded ADNI-1, ADNI-GO, and ADNI-2 studies that have been com...

Cystic fibrosis (CF), a life-shortening genetic disease, is marked by acute episodes during which symptoms of lung infection increase and lung function decreases. These pulmonary exacerbations are treated with varying antibiotics for varying time periods based on need...

The purpose of this study is to establish a registry of patients with pancreatic diseases. Patients included in the registry may include those with: pancreatic cancer, precancerous lesions of the pancreas, inflammatory lesions of the pancreas, cystic lesions of the panc...

This comprehensive genomic analysis and biospecimen repository study incorporates Next Generation Sequencing (NGS) of archival tumor tissue from 200 subjects with metastatic urothelial cancer in support of several parallel goals. The immediate goal involves generatio...

This phase II MATCH trial studies how well treatment that is directed by genetic testing works in patients with solid tumors or lymphomas that have progressed following at least one line of standard treatment or for which no agreed upon treatment approach exists. Gene...

This phase III ALCHEMIST trial studies genetic testing in screening patients with stage IB-IIIA non-small cell lung cancer that has been or will be removed by surgery. Studying the genes in a patient's tumor cells may help doctors select the best treatment for patient...

The purpose of this study has evolved and expanded since its inception. Originally the intent was to establish the functional, molecular and genetic profile of fibroblasts from Fibromuscular Dysplasia (FMD) patients as compared to carefully matched control subjects. Whi...

The initial objective of this protocol is to assemble a well-documented group of patients with confirmed diagnoses of the erythropoietic protoporphyrias, including autosomal recessive Erythropoietic Protoporphyria (EPP) and X-Linked Protoporphyria (XLP) for clinical, bi...

The purpose of this study is to test whether a focused questionnaire and laboratory tests can better define risk factors associated with possible genetic porphyria. The investigators hypothesize that the genetic carrier state of acute porphyria is distinctive enough t...

Congenital heart defects (CHD) are the most common major human birth malformation, affecting ~8 per 1,000 live births. CHD are associated with significant morbidity and mortality, and are second only to infectious diseases in contributing to the infant mortality rate. C...

Cholestasis is a condition in which bile is not properly transported from the liver to the small intestine. Cholestasis can be caused by an array of childhood diseases, including the genetic diseases Alagille syndrome (ALGS), alpha-1 antitrypsin (a-1AT) deficiency, bile...

Little is known about the factors that cause biliary atresia nor the factors that influence disease progression. The purpose of this study is to collect the pertinent clinical information, genetic material and body fluid samples to enable investigators to address the fo...
