Acute liver failure (ALF) is a rare but devastating syndrome. It is defined as the development of hepatic necrosis associated with hepatic encephalopathy and coagulopathy within 8 weeks of the onset of liver disease without evidence of chronic liver disease. Table 1. In humans with acute liver failure, >50% hepatocyte loss is required for significant activation of HPCs, and the number of HPCs is also inversely correlated with the number of Ki67+ hepatocytes, suggesting that unlike some animal models, human HPC activation depends on both hepatocyte loss and decreased proliferation (13, 14). The diagnosis of galactosemia should be considered in newborn or young infant with any of the following features: failure to thrive, jaundice, hepatomegaly, vomiting, hypoglycemia, convulsions, cataract, bleeding diathesis, renal tubular acidosis .

In another attempt to model KMT2A-AFF1 infant leukemia, Barrett et al. acute liver failure (alf) is a rare but potentially devastating process that often leads to urgent liver transplantation when it is believed that liver regeneration is unlikely. Although this study was the first that indeed produced a KMT2A-AFF1-driven pro-B-ALL, the disease did not develop in "infant" or newborn mice . In many cases, the etiology of NALF remains unknown.
