Generalized mosaicism for TSC2 mutation in isolated Lymphangioleiomyomatosis
2019
Lymphangioleiomyomatosis (LAM) is a rare, slowly progressive pulmonary disease, causing cystic lung destruction and respiratory failure. It affects predominantly premenopausal women, and rarely men. It can occur as a sporadic condition (sporadic LAM) or in association with Tuberous Sclerosis Complex (TSC-LAM) [1]. LAM is caused by biallelic inactivation of the tumor suppressor gene TSC2 in LAM cells, which leads to hyperactivation of mTORC1, resulting in anabolism and LAM cell proliferation [2]. Sirolimus and everolimus, mTORC1 allosteric inhibitors, have been shown to retard progression of LAM [3].
