Male and females between the ages of 12 months - 5 years at the time of treatment\n2. A molecularly confirmed diagnosis of SPG47 (confirmed by a CLIA certified, CE-marked, or equivalent lab): Genomic DNA mutation analysis demonstrating bi-allelic pathogenic variants in the AP4B1 gene.\n3. Proband must have features of neurologic dysfunction by clinical history and physical examination.\n4. Stable doses of concomitant medications such as anti-spasticity medications, anti-epileptic medications, behavioral management medications, sleep medications, and special diets, supplements or nutritional support for at least 3 months prior to Screening. If recent changes (\\\u003C 3 months) in medications, the participant may be allowed per Investigator judgement.\n5. Proband must be fully vaccinated per Centers for Disease Control recommendations for childhood vaccinations.\n6. Two competent custodial parents\u002Fguardians with legal capacity (legally acceptable representatives) to execute an Institutional Review Board\u002FIndependent Ethics Committee (IRB\u002FIEC) approved consent for medical research must be able to participate in the consent process. If only one parent has sole custody to consent for medical research, then that parent must be able to actively participate in the consent process.\n7. Legally acceptable representatives must be able to attend all scheduled study visits and provide feedback regarding the participant's symptoms and performance as described in the protocol.\n8. Legally acceptable representatives agree not to post any of the participant's personal medical data or information related to the study on any website or social media site (e.g., Facebook, Instagram, Twitter, YouTube, etc.) until notified that the study is completed.\n9. Proband and the proband's family must demonstrate ability to travel to the study center. For the first 30 days post treatment probands will need to stay within a 100-mile radius from the treatment center.\n\nExclusion Criteria:\n\n1. Inability to participate in the clinical evaluation as determined by the principal investigator.\n2.

Bleeding disorder or any other medical condition or circumstance in which a cisterna magna or lumbar puncture is contraindicated according to local institutional policy.\n5. Documented cardiomyopathy or significant congenital heart abnormalities.\n6. Inability to be safely sedated in the opinion of the clinical anesthesiologist.\n7.

Any known history and\u002For family history of hemophagocytic lymphohistiocytosis (HLH) or multisystem inflammatory syndrome (MIS)\n9. Concomitant illness or requirement for chronic drug treatment that in the opinion of the investigator creates unnecessary risks for gene transfer.\n10. Concomitant chronic drug treatment that would cause clinically significant interactions with immunosuppressive agents used in the study.\n11. Any item which would exclude the participant from being able to undergo magnetic resonance imaging (MRI) according to local institutional policy.\n12. Any other situation that would exclude the participant from undergoing any other procedure required in this study.\n13. Visual or hearing impairment sufficient to preclude cooperation with neurodevelopmental testing.\n14. The presence of significant non-SPG47 related central nervous system (CNS) impairment or behavioral disturbances that would confound the scientific rigor or interpretation of results of the study.\n15.
