The c.1640G>C (p.G547A) alteration is located in exon 3 (coding exon 3) of the ZNF404 gene. This alteration results from a G to C substitution at nucleotide position 1640, causing the glycine (G) at amino acid position 547 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
