The c.305C>G (p.S102C) alteration is located in exon 3 (coding exon 3) of the SLC35F3 gene. This alteration results from a C to G substitution at nucleotide position 305, causing the serine (S) at amino acid position 102 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
