| | Defective Enzyme Degradation in Johanson-Blizzard Syndrome (Site not responding. Last check: ) |
 | | The Johanson-Blizzard syndrome (JBS [OMIM 243800]), names not unfamiliar to GGH readers, is an autosomal recessive disorder characterized by congenital exocrine pancreatic insufficiency, mental retardation, facial abnormalities, and various other malformations. |
 | | Interestingly, several E3 ubiquitin ligases have been implicated in genetic disease, ie, UBE3A in Angelman syndrome, parkin in recessive juvenile parkinsonism, and VHL in von Hipple-Lindau disease. |
 | | Deficiency of UBR1, a ubiquitin ligase of the N-end rule pathway, causes pancreatic dysfunction, malformations and mental retardation (Johanson-Blizzard syndrome). |
