Filter by:Both Neurofibromatosis type 1 (NF1) and Tuberous Sclerosis Complex (TSC) are highly heterogeneous diseases. Cognitive features seem to vary widely even between family members carrying the same mutation. This phenotypic variability is not well understood, but is generally assumed to be caused by modifier genes which regulate the affected pathways. However, recent studies brought forward an alternative explanation for the phenotypic variability. Post-mortem studies showed that second hit mutations causing loss of the second ('healthy') allele are more widespread than previously believed. These loss of heterozygosity (LOH) mutations cause bi-allelic loss of the disease-linked gene and are known to cause the gross of somatic features in both diseases (like neurofibromas and hamartomas). Hence, it could be the stochastic occurrence of second-hit mutations in the brain are the cause of the variable cognitive phenotypes. To investigate to what extent these LOH mutations in the brain contribute to the phenotype and to what extent this variation is due to genetic modifiers factors is unknown. The investigators therefore propose to elucidate this variability by comparing the correlation of cognitive features of monozygotic twins with NF1 or TSC to healthy twins in the population. If modifier genes are the cause of the variability of cognitive features in NF1 and TSC the investigators expect that the variability in cognitive tests in monozygotic twins is the same as monozygotic twins in the healthy population. However, if the variability is caused by the occurrence of LOH mutations, the investigators expect to have a lower correlation in our monozygotic patients compared to the healthy twins.
This is a prospective study through the NF clinic at Massachusetts General Hospital that will examine the relationship between psychosocial factors, health literacy, and satisfaction with the medical visit in adults with NF1, NF2, and Schwannomatosis. A total of 89 participants will be enrolled in the study.
A monocenter pilot study on the acceptability and feasibility of a functional MRI protocol in children with NF1 with or without reading disabilities.
This phase I trial studies the side effects and best dose of pomalidomide in treating younger patients with tumors of the brain or spine (central nervous system) that have come back or are continuing to grow. Pomalidomide may interfere with the ability of tumor cells to grow and spread and may also stimulate the immune system to kill tumor cells.
Background: Neurofibromatosis type 1 (NF1) is a disorder that can cause plexiform neurofibromas (PNs). These are tumors that grow along nerves. Some PNs cause serious health problems. PNs often can t be operated on because of their large size, location, or number. There are no effective treatments known for people with NF1 and PNs. Researchers want to test if the drug selumetinib (AZD6244 hydrogen sulfate) causes PNs to shrink or slows down their growth. Objectives: To test if selumetinib helps treat PNs. To test how the body handles selumetinib and how it affects peoples symptoms. Eligibility: People ages 18 and older with NF1, with an inoperable PN that causes morbidity or is growing Design: Participants will be screened with: Medical history and physical exam Blood, urine, and heart tests Eye exam MRI: They lie in a machine that takes pictures of the body. PN biopsy: A small piece of the tumor is removed by a large needle. Questionnaires Participants will swallow selumetinib capsules every 12 hours for several 28-day cycles. The capsules are taken with a full glass of water on an empty stomach. Participants may have only water for 2 hours before and 1 hour after each dose. Participants will keep a drug diary. They will continue taking the drug as long as they tolerate it and their disease doesn t progress. Participants will have several visits throughout the study. These will include repeats of the screening tests. Participants will have a final visit after they stop taking selumetinib.
A national, multicenter, randomized, transverse clinical trial, estimating the existence of phonological deficits in children with NF1 children compared with control children without NF1 with the same reading level.
Background: - Some people with cancer have solid tumors. Others have refractory leukemia. This may not go away after treatment. Researchers want to see if a drug called TURALIO(R) can shrink tumors or stop them from growing. Objectives: - To find the highest safe dose and side effects of TURALIO(R). To see if it helps treat certain types of cancer. Eligibility: - People ages 3-35 with a solid tumor or leukemia that has returned or not responded to cancer therapies. Design: - Participants will be screened with: - Medical history - Physical exam - Blood and urine tests - Heart tests - Scans or other tests of the tumor - Participants will take TURALIO(R) as a capsule once daily for a 28-day cycle. They can do this for up to 2 years. - During the study, participants will have many tests and procedures. They include repeats of the screening tests. Participants will keep a diary of symptoms. - Participants with solid tumors will have scans or x-rays. - Participants with leukemia will have blood tests. They may have a bone marrow sample taken. - Some participants may have a biopsy. - When finished taking TURALIO(R), participants will have follow-up visits. They will repeat the screening tests and note side effects.
This study will look at the feasibility of using magnetic resonance fingerprinting (MRF) in children, adolescents and young adults (AYA) with and without brain tumors. This study will also look at subjects with and without neurofibromatosis type 1(NF1), a genetic disorder that affects the growth of nervous system cells. Further, it will explore potential ways of using of MRF signal measurements in children, adolescents, and young adults with brain tumors, including tissue characterization, looking at whether the treatment was effective, and finding metastasized tumors of unknown origin (occult tumors). To explore the feasibility and potential applications of MRF, this study will recruit up to 80 subjects but will stop once 10 subjects have usable data in each of six groups.
The aim of this research is to adapt the NF-specific adult version of the Skype 3RP for use with adolescents, and to test its feasibility, acceptability, and preliminary effect in improving quality of life, and in decreasing stress and psychological distress.
This trial is evaluating the use of oral Everolimus to determine if there is a reduction in the size of the disfiguring cutaneous lesions in patients with Neurofibromatosis 1 over a 6 month period. The evaluation will be done by 3D photography measuring volume with the LIFEVIZ Micro system.
