The c.485C>G (p.S162C) alteration is located in exon 4 (coding exon 4) of the CXCL16 gene. This alteration results from a C to G substitution at nucleotide position 485, causing the serine (S) at amino acid position 162 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
