Genes affected

TRIM21 (HGNC:11312): (tripartite motif containing 21) 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. The encoded protein is part of the RoSSA ribonucleoprotein, which includes a single polypeptide and one of four small RNA molecules. The RoSSA particle localizes to both the cytoplasm and the nucleus. RoSSA interacts with autoantigens in patients with Sjogren syndrome and systemic lupus erythematosus. Alternatively spliced transcript variants for this gene have been described but the full-length nature of only one has been determined. [provided by RefSeq, Jul 2008]

Feb 22, 2024

The c.895T>C (p.W299R) alteration is located in exon 7 (coding exon 6) of the TRIM21 gene. This alteration results from a T to C substitution at nucleotide position 895, causing the tryptophan (W) at amino acid position 299 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
