Neurogenetic Disorders

The objective of this project is to develop a Neurogenetics patient database and bio repository - which includes clinical information regarding history, physical examination, laboratory testing including genetic testing (NextGen sequencing including whole exome and whole genome sequencing, SNParray, etc.), neuroradiology studies, neurophysiology studies - all ordered as clinically deemed appropriate, natural history from clinical longitudinal follow-up and to use de-identified information from this registry/ repository, when appropriate for clinical and translational research.

This study evaluates a diagnostic support platform, DIAGEN-IA, designed to identify pediatric neurological diseases with a genetic basis. Conducted at Carlos Van Buren Hospital in Chile, it aims to determine if the platform reduces inappropriate referrals to clinical geneticists, improves diagnostic evaluations, enhances referral quality, and increases user satisfaction. A prospective before-and-after design will compare outcomes across two phases: baseline data collection and an intervention phase using DIAGEN-IA. Healthcare professionals will use the platform to guide referrals and diagnostic studies. Outcomes include referral appropriateness, completeness of evaluations, quality of referrals, and user satisfaction.

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
