Genes affected

TRIM13 (HGNC:9976): (tripartite motif containing 13) This gene encodes a member of the tripartite motif (TRIM) family. The TRIM motif includes three zinc-binding domains, a RING, a B-box type 1 and a B-box type 2, and a coiled-coil region. This gene is located on chromosome 13 within the minimal deletion region for B-cell chronic lymphocytic leukemia. Multiple alternatively spliced transcript variants have been found for this gene.

TRIM13 links:

DLEU2 (HGNC:13748): (deleted in lymphocytic leukemia 2) This locus represents a microRNA host gene and also produces long alternatively spliced non-coding RNAs. This genome region was observed to be deleted or epigenetically suppressed in leukemia, and was implicated as a negative regulator of cell proliferation. However, an alternative transcript produced at this locus was also found to promote progression through the cell cycle via angiotensin I converting enzyme 2 and cyclin D1.

The c.313C>T (p.L105F) alteration is located in exon 4 (coding exon 2) of the TRIM13 gene. This alteration results from a C to T substitution at nucleotide position 313, causing the leucine (L) at amino acid position 105 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
