Uridine Deficiency (Replacement) (N/A)

Target
N/A
Molecular classification
Metabolic Replacement, Pyrimidine Nucleotide
01

Overview

Uridine deficiency, in the context of replacement therapy, refers to a systemic lack of uridine nucleotides due to impaired de novo pyrimidine biosynthesis, most commonly seen in hereditary orotic aciduria. Uridine replacement, typically using uridine triacetate, aims to restore intracellular pyrimidine pools, bypassing the defective UMPS enzyme and enabling normal nucleotide synthesis. This approach is used to manage the symptoms and complications of UMPS deficiency.
