Genes affected

TRIM26 (HGNC:12962): (tripartite motif containing 26) The protein encoded by this gene is 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. The protein localizes to cytoplasmic bodies. Although the function of the protein is unknown, the RING domain suggests that the protein may have DNA-binding activity. The gene localizes to the major histocompatibility complex (MHC) class I region on chromosome 6. Alternatively spliced transcript variants encoding the same protein have been found for this gene.

The c.1558C>T (p.R520W) alteration is located in exon 10 (coding exon 7) of the TRIM26 gene. This alteration results from a C to T substitution at nucleotide position 1558, causing the arginine (R) at amino acid position 520 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
