This is the first description of an AAV-based gene replacement therapy for TSC type 2.
“This is the first description of an AAV-based gene replacement therapy for TSC type 2, whose further development will be particularly beneficial to TSC type 2 patients currently subjected to a regimen consisting of periodic administration of therapeutic drugs (e.g.rapamycin analogs), as gene replacement therapy would require a single AAV injection.”

A mini-gene approach showed that intravenous injection of AAV9-mini-TSC2 in a TSC2-mouse model greatly extended survival, while reducing brain pathology.
“Recently, a mini-gene approach showed that intravenous injection of AAV9-mini-TSC2 in a TSC2-mouse model greatly extended survival, while reducing brain pathology [111].”

“We felt it was also important to retain the hamartin-binding domain at the N terminus, as hamartin and tuberin function together as a complex with Tre2-Bub2-Cdc16 (TBC) 1 domain family, member 7 (TBC1D7) to accelerate guanosine triphosphate (GTP) to guanosine diphosphate conversion of Rheb-GTP (3, 22).”

“Therefore, there is a clear need to identify other therapeutic approaches for TSC. Adeno-associated virus (AAV) vectors have been used widely in clinical trials for many hereditary diseases with little-to-no toxicity, long-term action in nondividing cells, and improvement in symptoms ( 9 – 11 ).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
