The c.209G>A (p.G70D) alteration is located in exon 3 (coding exon 1) of the ZNF71 gene. This alteration results from a G to A substitution at nucleotide position 209, causing the glycine (G) at amino acid position 70 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
