Anosmin 2, pseudogene (ANOS2P)

ANOS2P (Anosmin 2, pseudogene) is a transcribed but non-functional pseudogene on the Y chromosome, formerly known as KAL-Y or KALP. It is a degraded homolog of the X-linked *ANOS1* gene, which encodes anosmin-1, a protein involved in neuronal development and associated with X-linked Kallmann syndrome. ANOS2P contains frameshift and premature stop codons that render it non-coding and non-functional as a protein product. Current nomenclature (endorsed by HGNC) is intended to clearly distinguish this pseudogene from the functional *ANOS1*, which is a gene of clinical and biological significance. ANOS2P is not a receptor, enzyme, transporter, transcription factor, or any other class of functional therapeutic target. Its mention typically arises in genetic and evolutionary studies rather than drug discovery or clinical research.
