The c.1351A>G (p.S451G) alteration is located in exon 4 (coding exon 3) of the SLFN12 gene. This alteration results from a A to G substitution at nucleotide position 1351, causing the serine (S) at amino acid position 451 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
