Prune Belly Syndrome: Mechanisms of Filamin A Mutations
Project Summary The overall goal of this project is to expand the knowledge on the genetic basis and molecular mechanisms of Prune Belly Syndrome (PBS), a severe human multi-system congenital urologic anomaly with muscle and connective tissue deficiencies. Hallmark clinical features of PBS include the triad of 1) wrinkled `prune' belly due to hypoplastic or absent abdominal wall skeletal musculature, 2) megacystis secondary to bladder smooth muscle pathology, and 3) bilateral undescended testes. We discovered three gain-of-function missense mutations in the X-linked gene filamin A (FLNA) causing syndromic and isolated PBS. FLNA is an abundant intracellular actin-crosslinking protein that…
