 | Tiny change in checkpoint protein hastens onset of liver failure in genetic disease | |
HOUSTON -- A single change in the genetic code for a checkpoint enzyme reduces its activity in the cell and results in rapid and early liver failure in children born with alpha-1 antitrypsin deficiency – an inherited disorder that can cause serious lung disease in adults and liver failure in infants, children, and adults, said researchers from Baylor College of Medicine and the University of Florida in a recent report in the journal Hepatology. |
