The c.202G>C (p.V68L) alteration is located in exon 4 (coding exon 3) of the IFI27L1 gene. This alteration results from a G to C substitution at nucleotide position 202, causing the valine (V) at amino acid position 68 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
