HOGA1 (Q86XE5) variants and mutations

HOGA1 (also known as Q86XE5) is a human protein-coding gene encoding a 4-hydroxy-2-oxoglutarate aldolase, mitochondrial protein. It catalyzes the final step of hydroxyproline breakdown in mitochondria, splitting 4-hydroxy-2-oxoglutarate into glyoxylate and pyruvate. Biallelic loss of function causes primary hyperoxaluria type 3, which can lead to excess urinary oxalate and recurrent calcium oxalate kidney stones. This analysis covers 648 HOGA1 variants and mutations. Of these, 98% have computational variant effect predictions. Disease context includes primary hyperoxaluria type 3, primary hyperoxaluria, and Hyperoxaluria. Example HOGA1 variants include M1I, M1R, and L2M.
