chronic lymphocytic leukemia up-regulated 1

Expression of this gene has been shown to be upregulated in some individuals with chronic lymphocytic leukemia (CLL), and has been used for prognostic and diagnostic purposes. This gene was originally identified as a human-specific putative protein-coding gene due to the presence of a peptide (PAp00140670, HIIYSTFLSK) that could have supported translation at this locus. This peptide is not present in more recent builds of PeptideAtlas, and the presence of a protein product at this locus has not been independently verified.
