The c.854C>G (p.S285C) alteration is located in exon 3 (coding exon 2) of the C14orf93 gene. This alteration results from a C to G substitution at nucleotide position 854, causing the serine (S) at amino acid position 285 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
