PIK3CA-related overgrowth spectrum (PROS) is a group of rare genetic disorders with asymmetric overgrowth caused by somatic mosaic mutations in PI3K-AKT-mTOR pathway that encompass a heterogeneous group of rare disorder that are associated with the appearance of overgrowth.

We demonstrated the following: (a) that PROS cells are dependent on AKT; (b) the advantage of inhibiting the pathway immediately downstream of PI3K to circumventing problems depending on multiple classes a PI3K kinases; and (c) that PROS patients benefit from inhibition of AKT rather than mTOR.
Post-zygotic activating mutations in PIK3CA and other genes encoding members of PI3K-AKT-mTOR pathway have been found in various overgrowth syndromes that have been grouped together as PIK3CA-related overgrowth spectrum (PROS).
Our findings expand upon the recently proposed "PIK3CA-related overgrowth spectrum" associated with PIKC3A mutations and PI3K hyperactivation, adding constitutional PIK3CA mutations as an underlying cause of megalencephaly and macrosomia in newborns.
Of note, PI3K pharmacological blockade resulted in a significant reduction of the proliferation rate in culture, suggesting that inhibition of PI3K might prove beneficial in future therapies for PROS patients.
