A missense variant in DGKG as a recessive functional variant for hepatic fibrinogen storage disease in Wagyu cattle.

ABSTRACT: Hepatic fibrinogen storage disease (HFSD) was diagnosed in a 5-month-old Wagyu calf with a history of recurrent respiratory disease. It was characterized by lethargy, dehydration, acidemia, and increased liver enzyme activities. Histologically, disseminated hepatocytes were swollen and showed a single, sharply demarcated, faintly eosinophilic cytoplasmic inclusion with a ground-glass appearance, with the nucleus in an eccentric position. Cytoplasmic inclusions did not stain with the periodic acid-Schiff (PAS) reaction. Using a rabbit polyclonal antibody against fibrinogen, the cytoplasmic vacuoles in the hepatocytes stained intensely. Electron microscopy disclosed hepatocytes with membrane-bound cytoplasmic inclusions filled with fine granular material interspersed with a few coarse-graine
