Leucine rich repeat containing 40 pseudogene (None established; often referenced by the Ensembl identifier (ENSG00000270421) or as "LRRC40 pseudogene.")

The "leucine rich repeat containing 40 pseudogene" is a DNA segment resembling the functional *leucine rich repeat containing 40* (LRRC40) gene, but with mutations such as frameshifts or premature stop codons that prevent production of a functional protein[4][6]. Pseudogenes arise either by gene duplication/retrotransposition or by disabling mutations in a previously functional gene[2][6]. In humans, pseudogenes are prevalent and may complicate genome annotation and genetic analysis, but most do not have direct functional or therapeutic relevance[6]. For context, the **LRRC40 gene** (distinct from the pseudogene) encodes a protein believed to participate in protein-protein interactions, contains leucine-rich repeats, and is conserved across many species[1]. However, the pseudogene variant is nonfunctional and does not produce protein; any biological effects would be through RNA interactions, which are not well-characterized for this locus[2][6]. If you are seeking information about a *therapeutic target*, you should refer to the functional **LRRC40 protein** and not the pseudogene. The presence of "pseudogene" in the canonical designation is a clear indication of nonfunctionality in classical molecular biology and drug targeting contexts[4][6].
