Collection Method: clinical testing

The c.778G>A (p.V260M) alteration is located in exon 4 (coding exon 2) of the SLFNL1 gene. This alteration results from a G to A substitution at nucleotide position 778, causing the valine (V) at amino acid position 260 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
