PRTFDC1 (Phosphoribosyl Transferase Domain Containing 1): PRTFDC1 is an enzyme involved in the purine salvage pathway, which recycles purines from degraded DNA and RNA to synthesise new nucleotides. This role in nucleotide metabolism indicates it is important for cell proliferation and DNA repair. Alterations in this pathway can affect cellular energy balance and genomic stability, with potential implications for metabolic health and the DNA damage response.
