Genes affected
CLLU1 (HGNC:29841): (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. For this reason, this gene is being represented as non-coding. Sequence comparisons to other primates indicates that no other primate is predicted to contain an open reading frame.

The c.124C>G (p.L42V) alteration is located in exon 2 (coding exon 2) of the CLLU1OS gene. This alteration results from a C to G substitution at nucleotide position 124, causing the leucine (L) at amino acid position 42 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
