May 18, 2023

The c.832A>G (p.M278V) alteration is located in exon 2 (coding exon 1) of the SLFN12 gene. This alteration results from a A to G substitution at nucleotide position 832, causing the methionine (M) at amino acid position 278 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
