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.

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -9 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.021131575).
BS1
Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.000493 (75/152198) while in subpopulation NFE AF= 0.000838 (57/68032). AF 95% confidence interval is 0.000664. There are 0 homozygotes in gnomad4. There are 28 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
BS2
High AC in GnomAd4 at 75 AD gene.

The c.2212A>G (p.I738V) alteration is located in exon 16 (coding exon 16) of the SART3 gene. This alteration results from a A to G substitution at nucleotide position 2212, causing the isoleucine (I) at amino acid position 738 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
