Active clinical trials for "Costello Syndrome"

Background: RASopathies are a group of genetic diseases that affect a child s development. They cause physical, cognitive, and behavioral symptoms. Caring for a child with a RASopathy can be stressful. Acceptance and Commitment Therapy (ACT) is a therapy that helps people become more aware and accepting of difficult thoughts and feelings. ACT has been found to be helpful for parents with high parenting stress. Objective: To find out if Acceptance and Commitment Therapy (ACT) can help caregivers of children with a RASopathy better cope with parenting stress. Eligibility: People aged 18 years or older who care for a child (younger than 18 years) with a RASopathy. The child must live with the caregiver at least 50% of the time. Design: The study is fully remote. Participants need a mobile device that can play audio and video and connect to the internet. They can borrow an iPod if needed. Participants will download a free app called MetricWire. They will use this app to watch videos and answer questions. The first 8 participants will be in a pilot study. They will receive the ACT intervention starting the first week after they begin the study. After the pilot study, we will start a new phase called the randomized trial. In this phase, participants will have a 50-50 chance of being in the group that will start the intervention right away or the group that will start the intervention after about 2 months. Participants will fill out surveys on 5 random days each week. These surveys have 7 questions and take about 2 minutes. They will also fill out 3 longer questionnaires: once before ACT begins, once just after the 8-week study period, and once about 3 months later. Questions will cover topics including: Parenting stress Life satisfaction Self-compassion Uncomfortable feelings and thoughts Mindfulness Participants will take part in an 8-week ACT intervention. They will have one 75-minute session with an ACT coach in the first week. Participants will watch 9- to 17-minute videos each week. The videos talk about how to practice ACT techniques to cope with parenting stress. Participants will have 20- to 30-minute coaching sessions in weeks 3 and 6. The coach will help them practice exercises and work through any problems.

RASopathies are a group of syndromes, caused by variants of genes involved in the regulation of the Ras/MAP/ERK pathway. This intracellular transduction pathway profoundly affects embryogenic development, organogenesis, synaptic plasticity and neuronal growth. RASopathies are characterized by multi-organ involvement, growth delay, premature aging and haemato-oncological manifestations. Based on evidences provided by literature, cancer screening protocols are applied in some individuals affected by RASopathies, even though detailed information about prevalence and molecular pathogenesis of such tumors is still not clearly elucidate.

The RASopathies are a group of developmental disorders caused by genetic changes in the genes that compose the Ras/mitogen activated protein kinase (MAPK) pathway. New RASopathies are being diagnosed frequently. This pathway is essential in the regulation of the cell cycle and the determination of cell function. Thus, appropriate function of this pathway is critical to normal development. Each syndrome in this group of disorders has unique phenotypic features, but there are many overlapping features including facial features, heart defects, cutaneous abnormalities, cognitive delays, and a predisposition to malignancies. This research study proposes to collect and store human bio-specimens from patients with suspected or diagnosed RASopathies. Once obtained, blood and/or tissue samples will be processed for: metabolic function studies, biomarkers, genetic studies, and/or the establishment of immortalized cell lines. In addition, data from the medical record (including neuropsychological evaluations) and surveys will be stored to create a longitudinal database for research conducted at CCHMC or at other research institutions.

Background: RASopathies are a group of conditions caused by a genetic change. People with a RASopathy may have developmental issues, cognitive disability, poor growth, and birth defects. They may also have an increased risk for developing cancer. Researchers want to learn more. Objective: To learn more about RASopathies, how genes and environmental factors contribute to cancer development in people with RASopathies, and the best way to find these cancers and other conditions early or prevent them. Eligibility: People of any age who have or may have a RASopathy, and their family members. Design: Participants will complete questionnaires about their personal and family medical history. Their medical records will be reviewed. Participants will give blood and urine samples. They will give a saliva or cheek cell sample. Some samples will be used for genetic testing. Participants may have a skin biopsy. Participants may have a physical exam by the RASopathies study team. They may also have exams by additional specialists, such as dentists; urologists; ear, nose, and throat doctors; and neurologists. Participants may have computed tomography of the face and mouth. They may have an ultrasound of the abdomen. They may have a bone density scan. They may have skeletal and/or spine x-rays. They may have magnetic resonance imaging of the brain, low back, chest, and/or heart. They may be photographed. Participants may have other tests, such as sleep, brain and heart electrical activity, speech and swallow, metabolism, hearing, eye, and colon function tests. Participants may sign separate consent forms for some tests. Participation will last indefinitely. Participants may be contacted once in a while by phone or mail. They may have follow-up visits.

The objective is to collect skin biopsies rom patients with Costello syndrome to analyze the molecular mechanisms responsible for this syndrome caused by a mutation in the HRAS gene and the effects of this mutation on energy metabolism and mitochondrial physiology.
