The c.254C>G (p.S85C) alteration is located in exon 2 (coding exon 1) of the ZNF646 gene. This alteration results from a C to G substitution at nucleotide position 254, causing the serine (S) at amino acid position 85 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
