The c.2455T>C (p.C819R) alteration is located in exon 4 (coding exon 4) of the SLFN14 gene. This alteration results from a T to C substitution at nucleotide position 2455, causing the cysteine (C) at amino acid position 819 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
