The c.820G>C (p.A274P) alteration is located in exon 3 (coding exon 2) of the ZNF787 gene. This alteration results from a G to C substitution at nucleotide position 820, causing the alanine (A) at amino acid position 274 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
