The c.56G>A (p.G19D) alteration is located in exon 1 (coding exon 1) of the ZNF703 gene. This alteration results from a G to A substitution at nucleotide position 56, causing the glycine (G) at amino acid position 19 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
