Tyrosine metabolism, biosynthesis of unsaturated fatty acids, bile secretion, and purine metabolism were significantly enriched in the ADR-induced FSGS group [Figure 1]e.
Hawkinsinuria is a rare disorder of tyrosine metabolism. It is transmitted as an autosomal dominant trait with variable clinical expression and is typically associated with a defect of the 4-hydrophenylpyruvate dioxygenase enzyme.[10] A subset of patients with this disorder present with metabolic acidosis and failure to thrive early in life.
Hereditary tyrosinemia Type I (HTI) (OMIM 276700) is a rare inborn error of the tyrosine metabolism due to a deficiency of the enzyme fumarylacetoacetate (FAA) hydrolase in the tyrosine catabolic pathway (Figure 1) (1).
According to the KEGG metabolism network, two of them (citrate cycle and glyoxylate and dicarboxylate metabolism) belong to carbohydrate metabolism, one (glycerolipid metabolism) belongs to lipid metabolism, and five of them (phenylalanine metabolism, phenylalanine, tyrosine, and tryptophan biosynthesis, valine, leucine, and isoleucine biosynthesis, tyrosine metabolism, and glycine, serine, and threonine metabolism) are in the range of amino acid metabolism.
