Testis expressed 21, pseudogene (TEX21P)

TEX21P (Testis expressed 21, pseudogene) is annotated as a pseudogene in the human genome[1]. Pseudogenes are segments of DNA that resemble functional genes but typically do not encode an active protein product due to mutations or truncations. There is no evidence for TEX21P being expressed as a functional protein nor being associated with biological processes or disease mechanisms. It is not considered a therapeutic target, and there are no known drugs or clinical biomarkers related to this gene. Its only established characteristic is sequence similarity to other testis-expressed genes, but it remains non-functional in the current scientific literature[1].
