Sorting nexin 18 pseudogene 7 (SNX18P7)

Sorting nexin 18 pseudogene 7 (SNX18P7) is a human pseudogene related to the sorting nexin 18 gene (SNX18), which is involved in intracellular membrane trafficking through roles in the endosomal sorting system[4][6][7]. Unlike the functional SNX18 gene, SNX18P7 is noncoding, does not produce a functional protein, and has no known physiological or disease relevance. It cannot serve as a therapeutic target or biomarker. Sorting nexins as a family are involved in membrane trafficking, particularly through a characteristic PX (phox homology) domain, but SNX18P7, as a pseudogene, does not participate in these functions[2][4][9]. The closest functional homolog, SNX18, is a protein involved in membrane trafficking, and studies on SNX18 address the biological and disease roles of the family, not the pseudogene[2][10]. Multiple catalog entries and gene databases, such as GeneCards and Sigma-Aldrich, confirm SNX18P7 is a pseudogene and provide no evidence for functional transcription or translation, further supporting that it is not a target for drugs or therapeutic intervention[4][6][7]. There is nothing intrinsically "wrong" with the name or identification as a pseudogene, but SNX18P7 is not a druggable or biologically active target and should not be considered as such in therapeutic contexts[4][6][7].
