The c.821A>G (p.D274G) alteration is located in exon 6 (coding exon 5) of the ZNF287 gene. This alteration results from a A to G substitution at nucleotide position 821, causing the aspartic acid (D) at amino acid position 274 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
