Phosphomannomutase 2 pseudogene 2 (PMM2P2)

Phosphomannomutase 2 pseudogene 2 (PMM2P2) is a processed pseudogene in the human genome related to the functional gene PMM2 on chromosome 16. As a pseudogene, it does not produce an active enzyme or protein and has no known biological function, clinical implications, or drug interactions. It is distinct from PMM2, which encodes an essential enzyme for glycosylation[1][11]. PMM2P2 should not be confused with PMM2, the enzyme phosphomannomutase 2, which is associated with congenital disorders of glycosylation and clinical disease, and is a valid therapeutic target[4][7][12]. PMM2P2, as a pseudogene, lacks protein-coding capacity and clinical relevance.
