The c.17T>C (p.F6S) alteration is located in exon 1 (coding exon 1) of the IFNA13 gene. This alteration results from a T to C substitution at nucleotide position 17, causing the phenylalanine (F) at amino acid position 6 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
