A Natural History Study of Angelman Syndrome

The goal of this observational study is to learn about the natural progression of Angelman syndrome (AS) in children and adults with a confirmed genetic diagnosis of AS. The main questions it aims to answer are: * How do developmental skills, such as communication, motor abilities, and adaptive behaviors, change over a 1-year period in people with AS? * Are there specific patterns in brain activity or sleep that are associated with changes in AS symptoms over time? Participants will: * Attend 3 in-person and 2 virtual study visits over 1 year for assessments. * Complete tests and questionnaires about development, behaviors, and sleep with the help of their caregivers. * Undergo electroencephalograms (EEGs) to measure brain activity and wear a sleep-monitoring device at home (to collect actigraphy data).

Analysis of Early Neurodevelopmental Alterations in Bipolar Disorder Based on Cortical Organoid Models

Demonstrate the existence of neurodevelopmental alterations in organoids derived from samples of patients with bipolar disorder (BD) with a neurodevelopmental (ND) component, compared with patients with bipolar disorder (BD) without an ND component.

Safety and Efficacy of AAV9/AP4B1 (BFB-101) For Patients With AP4B1-related Hereditary Spastic Paraplegia Type 47 (SPG47)

Safety and Efficacy of AAV9/AP4B1 For Patients with AP4B1-related Hereditary Spastic Paraplegia Type 47 (SPG47): A Phase 1/2 Single-Center, Open-Label Study of Stereotactic Intra-cisterna Magna Administration. The goal of this clinical trial is to evaluate whether a gene therapy can safely treat children with SPG47, a rare genetic condition that causes progressive spasticity and developmental delays. The main questions it aims to answer are: * Is the gene therapy safe and well tolerated? * Does the gene therapy improve motor function and developmental outcomes? Participants will: * Undergo screening assessments to confirm eligibility * Receive a single dose of the gene therapy vector * Attend follow-up visits for safety monitoring and developmental assessments over the course of five years

Brain Imaging in Babies Study

The aims of the BIBS Study The Brain Imaging in Babies study (BIBS) aims to improve understanding of how a baby's brain develops from before birth, up until 3-4 years of age. Working with children from a variety of backgrounds and communities, the investigators use a combination of state-of-the-art diagnostic tools such as MRI scans alongside traditional behavioural assessments to capture the earliest information on infant brain development. The focus of the BIBS study MRI scanning is a safe way of producing detailed images using strong magnetic fields and radio waves. It does not use X-ray. Along with learning more about brain development in general, the investigators also try to identify features that may in future help predict whether a child will or will not develop traits of conditions such as Autism Spectrum Disorder (ASD) or Attention Deficit Hyperactivity Disorder (ADHD). Long-term, this may help target useful interventions early on, helping children who are most in need. Since COVID-19 arrived in the United Kingdom (U.K.) in 2020, the investigators have been given ethical approval to include testing for this infection in the mothers and children participating in the study. This may provide an opportunity to better understand how mother and baby respond to infections. The investigators particularly welcome mothers who have had a positive COVID-19 test during their pregnancy to join the study.
