Genetic clue to development of mouth ulcers in lupus

The results of a new study showed for the first time an association between a specific genetic pathway and the development of mouth ulcers in patients with Systemic Lupus Erythematosus (SLE). Linking the vascular endothelial growth factor (VEGF) genetic pathway with a specific disease characteristic among SLE patients represents an important step towards unravelling the genetic basis of different SLE clinical presentations.
