Adenosylhomocysteinase pseudogene 4 (AHCYP4)

Adenosylhomocysteinase pseudogene 4 (AHCYP4) is classified as a pseudogene, meaning it is a genomic DNA sequence similar to a functional gene but is typically non-coding and does not translate into a functional protein. It is not implicated in any known biological function, disease process, or therapeutic pathway. The functional homolog, AHCY, encodes S-adenosylhomocysteine hydrolase, an enzyme implicated in methylation processes and cancer, but AHCYP4 itself has no described role in health or disease[2]. No drugs, biomarkers, molecular mechanisms, or disease associations are documented for this pseudogene. For biomedical research or translational applications, the relevant gene is likely AHCY (S-adenosylhomocysteine hydrolase), not AHCYP4[2].
