Ethanolamine kinase 2 pseudogene

Ethanolamine kinase 2 pseudogene (ENSG00000274468) is a nonfunctional segment of DNA that shows sequence similarity to the functional ethanolamine kinase 2 gene but lacks the capability to encode a protein due to disabling mutations such as premature stop codons or frameshifts[2][1]. Pseudogenes are abundant in the human genome and generally considered genomic relics, although occasionally some pseudogenes may be transcribed and play limited regulatory roles, often by acting as non-coding RNAs or competitive endogenous RNAs in gene expression networks[3]. However, the majority of pseudogenes, including the ethanolamine kinase 2 pseudogene, do not have proven functional protein products and are not used as drug targets, disease markers, or clinical therapeutic entities[1][2][3]. Summary: ENSG00000274468 refers to a pseudogene—not a receptor, enzyme, transporter, or established molecular target—and should not be confused with its functional counterpart, ethanolamine kinase 2. It does not encode a protein, does not participate as a direct therapeutic target, and has no known clinical or pharmacological significance[2][1][3].
