Genes affected

SART3 (HGNC:16860): (spliceosome associated factor 3, U4/U6 recycling protein) The protein encoded by this gene is an RNA-binding nuclear protein that is a tumor-rejection antigen. This antigen possesses tumor epitopes capable of inducing HLA-A24-restricted and tumor-specific cytotoxic T lymphocytes in cancer patients and may be useful for specific immunotherapy. This gene product is found to be an important cellular factor for HIV-1 gene expression and viral replication. It also associates transiently with U6 and U4/U6 snRNPs during the recycling phase of the spliceosome cycle. This encoded protein is thought to be involved in the regulation of mRNA splicing.

FICD (HGNC:18416): (FIC domain protein adenylyltransferase) Enables several functions, including ATP binding activity; Hsp70 protein binding activity; and chaperone binding activity. Involved in protein adenylylation; regulation of IRE1-mediated unfolded protein response; and response to endoplasmic reticulum stress. Is integral component of endoplasmic reticulum membrane.

The c.2786A>G (p.Q929R) alteration is located in exon 19 (coding exon 19) of the SART3 gene. This alteration results from a A to G substitution at nucleotide position 2786, causing the glutamine (Q) at amino acid position 929 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
