SPG4 and SPG56 research
Project Status SPG4, September 2022
- A number of mice have been injected with either the SPAST vector or the control by the Baas Laboratory at Drexel University College of Medicine; preliminary data from injections is promising
- Four additional AAV9 vectors have been generated by the Sena-Esteves Laboratory at UMass Medical School for further testing
- Monthly breeding/injections will continue in order to obtain more robust and conclusive data.

SPG56 research in Qld
Abstract
Hereditary spastic paraplegia 56 (SPG56) is an extremely rare autosomal recessive disorder caused by mutations in the CYP2U1 gene, involved in fatty acid metabolism. SPG56 causes progressive spasticity in upper and lower limbs, though due to the rarity of this subtype of spastic paraplegia, the molecular causes remain unclear and no treatment or cure exists.
Here we describe the generation and validation of induced pluripotent stem cell (iPSC) lines from two unrelated patients with SPG56 and two heterozygous family members. These lines can be used to investigate the mechanisms driving progressive spasticity and evaluate the potential for gene replacement therapies.
