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.2504A>G (p.N835S) alteration is located in exon 17 (coding exon 17) of the SART3 gene. This alteration results from a A to G substitution at nucleotide position 2504, causing the asparagine (N) at amino acid position 835 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
