WP5501 - GNAQ p.R183Q drives capillary malformation - Homo sapiens

"Gαq-R183Q, when expressed in ECs [endothelial cells], establishes constitutively active PLCB3 signaling that leads to increased ANGPT2 and a pro-angiogenic, pro-inflammatory phenotype. EC-R183Q are sufficient to form enlarged [capillary malformation, CM]-like vessels in mice, and suppression of ANGPT2 prevents the enlargement. Our study provides the first evidence that endothelial Gαq-R183Q is causative for CM and identifies ANGPT2 as a contributor to CM vascular phenotype."
