Hyperoxaluria GRHPR (Domestic Short/Long Hair Type)



Test Overview:

A decrease in AGT or GRHPR enzymes. A rare disorder with symptoms including organ disorders/damage which can lead to damage of the eyes, bones, muscles, blood vessels and major organs including the heart. Affected kittens died of acute kidney disease between 5 and 9 months of age. Renal histopathology was consistent with nephrocalcinosis. Increased concentrations of L -glyceric acid and oxalate were observed in the urine from affected cats, and hepatic GRHPR activity was decreased suggestive of a condition analogous to human hyperoxaluria type II.
