C1D nuclear receptor corepressor pseudogene 4 (C1DP4)

C1D nuclear receptor corepressor pseudogene 4 (C1DP4) is annotated as a pseudogene and does not encode a functional protein[1][7]. Pseudogenes are genomic DNA sequences similar to typical genes but are non-functional due to mutations or lack of regulatory elements[2][5][8]. C1DP4 is related by sequence to the C1D nuclear receptor corepressor gene, which itself encodes a DNA-binding, apoptosis-inducing protein implicated in nuclear receptor signaling through corepression mechanisms[4]. However, the pseudogene C1DP4 is not known to have a biological function, and it is not considered a therapeutic target. There are no documented alternative names or aliases for C1DP4, and no evidence links it to specific diseases, biomarkers, drugs, or safety concerns. The existence of this pseudogene is mainly of genomic annotation interest rather than clinical or therapeutic relevance[1][2][7].
