Genes affected

KCNRG (HGNC:18893): (potassium channel regulator) This gene encodes a protein which regulates the activity of voltage-gated potassium channels. This gene is on chromosome 13 and overlaps the gene for tripartite motif containing 13 on the same strand. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Feb 2012]

KCNRG links:

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. [provided by RefSeq, Jul 2008]

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.131T>C (p.M44T) alteration is located in exon 1 (coding exon 1) of the KCNRG gene. This alteration results from a T to C substitution at nucleotide position 131, causing the methionine (M) at amino acid position 44 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
