The c.31T>C (p.F11L) alteration is located in exon 2 (coding exon 1) of the SLFN5 gene. This alteration results from a T to C substitution at nucleotide position 31, causing the phenylalanine (F) at amino acid position 11 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
