Somatic activating BRAF variants cause isolated lymphatic malformations

HGG Advances, 2022
Summary: Somatic activating variants in PIK3CA, the gene that encodes the p110α catalytic subunit of phosphatidylinositol 3-kinase (PI3K), have been previously detected in ∼80% of lymphatic malformations (LMs).1,2 We report the presence of somatic ...
