Collection Method:clinical testing

The c.2540T>A (p.V847E) alteration is located in exon 6 (coding exon 4) of the SLFN13 gene. This alteration results from a T to A substitution at nucleotide position 2540, causing the valine (V) at amino acid position 847 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
