The c.688T>G (p.S230A) alteration is located in exon 2 (coding exon 1) of the ZNF646 gene. This alteration results from a T to G substitution at nucleotide position 688, causing the serine (S) at amino acid position 230 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
