Genes affected

SLFN11 (HGNC:26633): (schlafen family member 11) Enables tRNA binding activity. Involved in several processes, including defense response to virus; negative regulation of G1/S transition of mitotic cell cycle; and replication fork arrest. Located in cytosol; nucleoplasm; and site of DNA damage. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.07516089).

Ambry Genetics

Mar 29, 2022

The c.2332C>G (p.R778G) alteration is located in exon 7 (coding exon 4) of the SLFN11 gene. This alteration results from a C to G substitution at nucleotide position 2332, causing the arginine (R) at amino acid position 778 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
