Argininosuccinate synthetase 1 pseudogene 7 (ASS1P7)

Argininosuccinate synthetase 1 pseudogene 7 (ASS1P7) is one of several named pseudogenes related to the functional gene *argininosuccinate synthetase 1* (ASS1), which encodes a key enzyme in the urea cycle and arginine biosynthesis[1][2][3][4][5]. The ASS1P7 pseudogene does **not produce a functional enzyme** and thus does not take part in metabolic or disease-related pathways. Only the ASS1 gene copy located on chromosome 9 encodes the functional protein, while other copies, including ASS1P7, are pseudogenes scattered throughout the genome and have no demonstrated biological or clinical function[1][3][4]. Therefore, ASS1P7 is **not an established molecular or therapeutic target**, does not interact with drugs, and has no associated disease roles, functions, or biomarker utility. The entry likely arises from bioinformatic annotation of duplicated, non-functional gene copies, and should not be treated as a real drug target. **Note:** All drug, disease, and function associations—including those related to citrullinemia, arginine biosynthesis, the urea cycle, therapeutic depletion, and cancer metabolism—refer to the functional ASS1 gene and not to this or any pseudogene[1][2][3][4][5].
