| Summary: | <b>Background/Objectives</b>: Tuberous sclerosis complex (TSC) is a rare, autosomal dominant genetic disorder caused by mutations in the <i>TSC1</i> and <i>TSC2</i> genes, which disrupt the regulation of the mammalian target of rapamycin (mTOR) pathway, a critical regulator of cellular growth. The disorder presents as a multisystem condition, with benign tumors (hamartomas) developing in organs such as the brain, skin, heart, kidneys, and lungs, leading to significant clinical variability and impact on quality of life. This review aims to summarize recent advances in the understanding of TSC pathogenesis and clinical variability and evaluate the therapeutic breakthroughs in targeted treatments. <b>Methods</b>: A narrative review was conducted using various available databases. We applied objective evaluation metrics, such as the impact factor of the journals and the citation count, to assess the quality of the studies. <b>Results</b>: Targeted therapies, particularly mTOR inhibitors (mTORis), have shown efficacy in reducing hamartoma size, improving neuropsychiatric symptoms, and enhancing patient outcomes. Despite these advances, variability in disease expression poses challenges in diagnosis and individualized management strategies. <b>Conclusions</b>: Challenges such as early diagnosis, optimizing long-term outcomes, and addressing residual unmet needs remain critical. Future research should prioritize precision medicine approaches and patient-centered care models within centers of expertise to improve treatment efficacy and quality of life for individuals with TSC. |
