Rare inherited disorders linked to the mammalian target of rapamycin (mTOR) pathway mutations cause tumors and developmental issues. Inhibiting mTOR complex 1 (mTORC1) shows promise for treating these conditions.
Area of Science:
- Genetics
- Developmental Biology
- Pharmacology
Background:
- Mutations in genes encoding upstream components of the mammalian target of rapamycin (mTOR) pathway cause rare inherited and developmental disorders.
- These disorders share overlapping clinical features, including tumor predisposition, localized overgrowth, and brain abnormalities.
Purpose of the Study:
- To review inherited and developmental disorders associated with mTOR pathway mutations.
- To discuss recent therapeutic advancements using mTOR complex 1 (mTORC1) inhibition.
Main Methods:
- Literature review of genetic disorders affecting the mTOR pathway.
- Analysis of clinical features and therapeutic strategies involving mTORC1 inhibitors.
Main Results:
- Hyperactivation of mTORC1 signaling is implicated in the pathogenesis of these disorders.
- Rapamycin and its derivatives are potential therapeutic agents.
Conclusions:
- mTORC1 inhibition represents a promising therapeutic avenue for rare inherited and developmental disorders.
- Further research into mTORC1-targeted therapies is warranted for these complex conditions.

When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
