Endothelial cell adhesion molecule pseudogene

The endothelial cell adhesion molecule pseudogene (ENSG00000254509) is a nonfunctional DNA sequence within the human genome that lacks the ability to encode a working protein. Pseudogenes are genetic elements that arose from once-functional genes through mutation or genomic rearrangement, ultimately losing coding potential due to frameshift mutations, premature stop codons, or sequence disruption. Most pseudogenes, including this one, evolve neutrally and do not participate in active cellular signaling or protein interactions. Although certain pseudogenes can play regulatory roles in gene expression, there is no evidence or annotation indicating such a role for ENSG00000254509. The name reflects homology to the endothelial cell adhesion molecule gene, but this locus encodes no active receptor or protein. It is not a therapeutic target, is not associated with disease roles, and is not used as a biomarker or drug target.
